product never arrived, shipped without tracking

For RGB Nokia 5110 LCD Board

Can't review the product as I never received it. Explanation I received was that I did not purchase shipping with tracking. It was not clear from the description that it will be shipped internationally without tracking number. The next shipping option was adding significant cost to the product. My loss, but do not recommend buying from this vendor if you have to ship internationally.

Response from μInventions | April 12, 2021

Hello Ivan, Its perfectly clear from the shipping options that there is a tracked option and a non tracked option. I offer the non tracked option for free at my own expense for people who do not mind waiting. You can get the tracked version for 2 dollars which is not the full price of the shipping company because I cover more than 50% of it to be affordable to costumers. I don't think 2 dollars would add a "significant cost" like you say. You're the first person to complain they haven't received it. I would have been able to help you if you messaged me further. I'm sorry you've had this experience

ESP-01 8266 on breadboard and easy flashing

For ESP-01 Breadboard Adaptor/Mount ESP8266

Getting an ESP-01 on a breadboard is pain. Flashing it is a pain. There are solutions, but I didn't have a good one to solve both at the same time. This little adapter board lets me go through flash/test cycles without having to disconnect/reconnect wires or move the esp-01 to a different rig to flash.
With a USB to serial adapter (5V power 3v3 logic and DTR/RTS) [https://www.adafruit.com/product/3309] I can now hit the 'upload' button in the Arduino IDE and the esp-01 is put into flash mode, and after the flashing completes it gets reset). I generally use easier to use dev boards where this is not an issue, but I sometimes do want to try things with cheap ESP-01 modules.

Also a seriously impressive neat packaging job, the mail truck would have to drive over the package to damage its contents.

Things I haven't tried yet:
- try powering the adapter board with a 3v3 usb2serial device (bypass the 5v->3v3 voltage regulator)
- run i2c on the d0/d2 pins

Note: if your usb to serial only has power/gnd/rx/tx you can still use this adapter board but you need to do some button press juggling (that's an ESP-01 thing)

Tiny and bright but one dead pixel

For WS2812-2020 8x8 Matrix 25*25mm

Arrived very quickly. Blindingly bright but had one dead pixel unfortunately And seemed to die after a couple of minutes. Otherwise 5 stars.

Response from μInventions | Sept. 7, 2020

Hello, I'm sorry this happened to you. It was working before I shipped it. Maybe it was damaged while it was being shipped. I'm willing to fix it if you want. Ill cover for the shipping fees. Please contact me
Thanks for the review

Happy little blinkers!

For LED Byte

A wonderful collection of little, drop-on-the-breadboard LEDs. Every time I need to debug a handful of things, I spend way too much time hunting for leds, resistors, and so on. No longer, I doubt I take these off my breadboards.

Thanks for the feedback, Chris!

A brilliant idea. And a great execution.

For LED Byte

Ever wanted to add a byte's worth of LEDs to an already existing project, maybe temporarily, in order to debug it? Even with a multi-LED package and a SIL set of resistors, it' still a lot of soldering. And then, you have to undo it all... But with this intelligent little board you get 8 LEDs and 8 current limiting resistors in the same shape and size as a 16-pin DIP chip. And for your money, you even get 8 easy to read numbers printed on the PCB... What more?

Great idea. A real time saver !

For ESP-01 Breadboard Adaptor/Mount ESP8266

Was happy to find this product. Really helps speed-up development of ESP-01 based projects when using a breadboard.

Good

For Trinket MØ Board

Product works as described. There is one little flaw: I saw some solder (balls) residue on the board.

Response from μInventions | June 10, 2020

Thanks for the feedback Cedric.
I've recently invested in an ultrassonic cleaner to get rid of the residues. Current and future boards are not gonna have this problem.

Cedric | June 10, 2020

Good

For LED Byte

Not much to it, works though so; Nice. The included headers are nice too. The resistors are chosen apropriately.

Response from μInventions | June 10, 2020

Thanks for the feedback Cedric.

Does exactly what it says

For LED Byte

Really useful little module to add some LEDs to a project quickly. I really like that the configuration (common anode/cathode) is marked on the PCB, most LED bargraphs don't do that. The different colors on offer are also a plus.

The delivery took just 2 weeks, which is pretty good for free delivery (and especially now).

Response from μInventions | June 4, 2020

Thanks for the feedback Kayla.
I appreciate it

Great little tool voor ESP-01

For ESP-01 Breadboard Adaptor/Mount ESP8266

This board is a very nice "tool" when you like to use an ESP-01 in breadboard setup.
Onboard DCDC converter and boot/reset buttons makes it even easier to use.

Very fast international shipping.

Great nifty board & smooth delivery with personal note!

For ESP-01 Breadboard Adaptor/Mount ESP8266

All Great here!
Even though it's a tiny piece of a board it's a real helper for me.
It does what its suppose to do :)

Thank you for the easy shipping & the personal note!

Best of luck with this and your future projects & products
Cheers,
Mario

Nice little breakout to put ESP-01 on a breadboard

For ESP-01 Breadboard Adaptor/Mount ESP8266

Very nicely priced board to put an ESP-01 directly into a breadboard
I can reocommend this board to anyone who does prototyping with the ESP01
