Tiny ESP32 WROVER pSRAM board

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!

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:

HydraESP32: HydraBus and ESP-32S

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.

HydraESP32 v1.1 Rev1 with ESP-32S is alive

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.

MicroUSB powered ESP8266 Oled Board

logo.jpgMike Rankin created this board with a tiny OLED display controlled by an ESP8266:

MicroUSB powered ESP8266 OLED Board

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:
