Tiny ESP32 board from the Kilobyte store on Tindie with optional battery header and pSRAM:
It’s a little ESP32 Board. Perfect for controlling or sensing stuff in the real world and sync it to the internet! Despite that it features the ESP32 WROVER Module. This means it got 4MB FLASH and 4MB RAM. That’s an absolute incredible amount of RAM. I honestly have no clue for what I will ever need 4MB in my embedded Projects.
Why did you make it?
I wanted a small ESP32 Board with the pSRAM and which works and doesn’t eat your whole time to get it working and find it’s issues and quirks.
I’ve used the CP2102 Serial converter because this is the one, which works the best way to program the ESP32. Even Espressif uses this serial converter on their own dev boards.
What makes it special?
It’s propably the smallest ESP32 Board with pSRAM. Despite the size it’s ideal for battery operation. It uses under 200uA in Deep Sleep mode!
thingSoC is an Open Source socket system for IoT development and has just launched a new Crowdy Supply campaign:
Build any IoT or Networked device you can imagine!
The thingSoC Grovey! platform gives you the freedom to choose from hundreds of existing sensors, actuators, and radios to quickly create new electronic systems, in plug together configurations that were not possible before. Easily mix together different CPUs, Radios, and Peripherals, like Servos, Motors, Relays, Sound and Lights, and then program them in your choice of Integrated Development Environments (IDE).
The thingSoC Grovey! series combines access to the Seeedstudio Grove system, and the Mikrobus “Click” system, to give you the widest selection of radios, sensors, and actuators available today.
The thingSoC Grovey Series files are available on GitHub:
The Espressif ESP32 features a 32-bit 240 MHz dual core processor with Wi-Fi and BLE. HydraBus created this shield for ESP-WROOM-32 or ESP-32S.
This shield can be used with or without HydraBus board, you can even cut HydraBus specific right side (on the line) to have a tiny ESP-WROOM-32 breakout board.

Mike Rankin created this board with a tiny OLED display controlled by an ESP8266:
I created this design as a challenge to make a design under 1″ x 1″ in size.
The hardware is an ESP-01 ESP8266 Wifi module, linear power supply, microUSB connector and a few oled display parts.
The design files and source code are available on GitHub:
Here is a video of the assembly and operation:

ESP32-WROOM-32 modules are in stock now! Again these are from the very first lot and with limited supply. To give chances to more developers to try them we will not allow more than 3 modules per order. This module is good only if you develop your own board. For these who are not good with […]
