perfect for Breadboarding

For Matrix Sanitizer

Firstly, good delivery times to half way around the world. This product is GREAT for breadboarding. In area, it is a quarter size (half length, half width) of a "normal" 8x8 matrix therefore fits better on a breadboard and still have access to a couple connection points either side, and more in a line for more advanced circuits and displays. The remapping of the matrix legs really does save your sanity.

So cool!

For Small PewPew Standalone

What a fun kit! Comes mostly assembled and tested .. I just had to solder in the LED matrix, which was already installed correctly. The pins were smashed in the post, but were easily straightened before soldering. I had some double-sided foam tape in my shop, so adding the battery pack on the back was easy. Seller was easily available by email. I would buy this kit again.

Very good dev board

For µGame 10 Python Game Console Kit

The packaging was correct and the delivery was fast.
The dev board is functional, but I noticed that the micro USB connector was moving (the brackets had not been welded). After 2 welds the problem has been solved.

Good Seller with amazing support.

For 16-pin Expander Shield for D1 Mini

I bought one of the 16 pin Expander Shields for a Project of mine, because the amazin D1 Mini sadly ran out of pins for me to use.
When I stumbled upon this board, I immediately ordered one to test. Shipping did take a while to germany, but it was a busy time with a few public holidays in between, so that's ok.
When I asked a Question about the board I got an answer pretty quick, that helped me immense, and even with my own stupidity, asking some stupid questions, I always got nice answers. When I finally found out, that one pin of the board was not functional, I was offered a replacement immediately.
All in all, I can definitely recommond this product and seller, as I tested out the functioning pins and everything works great. The Shield looks good on the D1 Mini and gives you a lot of pins for your projects.

I love it

For Rainbow Jellyfish Kit

The perfect mix of functional and fun. I originally ordered 3, but ordered 3 more, I love the different faces.

Amazing and interesting

For Rainbow Jellyfish Kit

So nice little circuit. Handling lost package and communication was so easy going, i hope to buy more staff from this guy.

Neat little learning tool for Python

For µGame 10 Python Game Console Kit

This is a nice little project to tinker with python. The screen is very nice and colour unlike many Arduino kits. Great fun.

Awesome little Things

For X-Pad, Buttons Shield for D1 Mini, Version 6.0

Currently developing micro/mini console using a microcontroller, and this thing could help me a lot. It is also cheap enough to send to my country. Thanks Deshipu

Good product

For 16-channel Servo Shield for D1 Mini, Version 2.0

Good product, the max problem are the pin to solder on board, was missing, so keep same from wemos or need to buy, no instructions, i saw from product pictures and hope no broken it, a the end the board sound good, I had test until now only with servo, I hope it's good too with strip led and both.

Hello, you should have received the stacking headers together with the device, as on the photo. If you didn't, then it's a packaging error and you should contact me through Tindie with your order number.

Well thought out and executed

For X-Pad, Buttons Shield for D1 Mini, Version 6.0

I've written button debouncing code in MicroPython, but this little device brings convenience to a new level. Buttons you press are latched on until the next read, a benefit I hadn't been expecting. The physical design is excellent, and the push-to-fit mounting for the D1 Mini greatly simplifies further construction. All in all a great little product that I'm looking forward to experimenting with.

Never underestimate the predictability of your expectations

For X-Pad, Buttons Shield for D1 Mini, Version 6.0

However this totally exceeded the expectations I had.
No matter how many buttons are pushed at the same time, it still reports the statuses to the perfection.
Kinda missing a proper driver although the communication is pretty straightforward : https://github.com/tobozo/ESP8266SDUpdater/blob/master/examples/OLEDiFOO/xpad8buttons.h

I'll be getting more ot those soon, especially looking forward to see the next model :)

It's a great little toy

For µGame 10 Python Game Console Kit

I've unpacked it , tested that it turns on, but didn't actually get to use it yet.
Leavening s review because tindie insists.
I wish there was documentation, e.g. what does the switch do and how to run games while tethered.

Response from Radomir Dopieralski | March 6, 2018

Hi, the documentation is linked from the sidebar of this page, you can also access it by visiting: http://ugame.readthedocs.io/
It is still a work in progress, so if you find anything in it missing, let me know and I will add it.

Great little dev board

For µGame 10 Python Game Console Kit

Very nice and compact design. Great python library and project. Makes prototyping little games and UI application very easy.

Manuel | Feb. 10, 2018

Excellent tiny console!

For µGame 10 Python Game Console Kit

It's amazing the detail and quality of this. I really like the form factor, the buttons and how easy it is to upload a sketch and play.
I like it a lot! And it's another excuse to learn Python!
Good work!

Joseph | Nov. 24, 2017

Very cool product. Works great!

For 8x8 LED Matrix Shield for D1 Mini

These work great. The chip is so much faster than the "standard" Wemos matrix shield. I'm using them with MicroPython and they work perfectly.

Marek | Oct. 13, 2017

Really great shield!

For X-Pad, Buttons Shield for D1 Mini, Version 6.0

Buttons shields looks really great, fully professional job!
Now time for tests :)
Fast shipping! Thanks :D

So glad I discovered this WeMOS D1 servo shield!!

For 16-channel Servo Shield for D1 Mini, Version 2.0

My grandson (6 yrs old) and I are planning on playing with servos and since I had a couple WeMOS D1, I went looking for a shield and discovered this one. Now I live in the US and I know international shipping can take some time, and this did. I waited a month and it never showed.

The day before I was going to email Deshipu, I got an email from him asking if I had recieved the boards yet (wow!!). When I told him I hadn't he asked me to send him the order number and he would ship out replacements. I offered to pay, but he would't hear of it. Wouldn't you know it, two days later I go out to the mail and there was the package. Fortunately I was able to email Deshipu before he mailed out the replacements.

Soldering the headers was a piece of cake. I downloaded the recommended library (you can find them in the documentation) connected the board to the WeMOS, attached a servo and ran one of teh sample programs and the servo started moving.

My grandson wants to set up sone 'spy' traps so the idea is to have a PIR on another WeMOS checking the hall. The WeMOS with the server will be on the ceiling with the servo holding some confetti. When someone goes by, the PIR will send a signal and the servo will open dropping the confetti (originally he wanted to drop something much heavier, but I talked him out of that idea - phew)

I was very impressed with Deshipu checking up on me before I had to contact him and being ready to ship off replacements. If only all businesses would run this way.

I highly recommend doing business with him.

Response from Radomir Dopieralski | July 16, 2017

Thank you very much for the review, and again sorry for the delay. I just wanted to clarify that the e-mail you initially got is not from me, it was probably an automated e-mail from Tindie itself.

a very nice add-on for WeMOS D1 mini for building robots

For 16-channel Servo Shield for D1 Mini, Version 2.0

The servo shields arrived in a short time (a couple of days), nicely packaged and all in good shape. I solder the headers, and start using it based on the very good documentation. It works as advertised. I've soldered two header-pins in the (external) power-holes for easy connecting external power supply.

The reason(s) I bought it, is that I like the small WeMOS D1 mini boards (I have a couple of them with some shields). I'll like to use the servo shield to build a small robot: body with moving arms, head turning on top of body and led-matrices as "eyes". My purpose is to investigate what may make the robot "social". I 'm try to use MicroPython instead of Arduino C/C++ (also for educational purposes). There is a driver for the PCA9685-chip used in the shield (see GitHub of Adafruit) and it works flawless. I'm still busy to setup the robot, so, I can't say yet if it will succeed.

I've read about "deshipu" in the WeMOS forum (and seen/used some work of him from GitHub) and was quite impressed. It was a nice surprise to see him on Tindie. I had no hesitating to buy from you.

After buying the shields, the owner "deshipu" sends me a message, politely asking what my intention was. Nice to see such an interest from the owner!

Would I recommend "deshipu" and his products to friends? Definitely YES.

A very necessary product and high quality to boot!

For 16-channel Servo Shield for D1 Mini

This is my first purchase on Tindie and I was not disappointed. The product itself is a necessary one - there are no equivalents that I can find anywhere. I'll be using the product to create a more compact animatronics driver than is possible with the arduinos I've used in the past. The added bonus of the wifi on the esp8266 is interesting too and might allow for simple live performance control. This board really opens up some intriguing possibilities. It fits nicely on top of the d1 minis and is very high quality (much more so than the minis themselves). The board is manufactured at OSHpark (at least this prototype I received is) and so is elegant and high quality. The pins used turned out to be very strong high quality also. This was a good thing as they arrived bent but I was able to fix them. After a quick email exchange the conclusion was the pin rows should be soldered by the customer in future.

In this prototype a trace needs to be cut to switch from esp routed power to external power - external power being a must for most scenarios of use I guess. In the future this will be a jumper I'm told, which will make this board even better.

Shipping was fast and inexpensive and thats important - hate to pay more for shipping than for the board.

This is a quality product, a necessary one in the market and a good, friendly seller.
_Strongly_ recommended.
