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)

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.

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.

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).

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
