In that pursuit [Andreas] over at Splitbrain sent in his latest project, Pinoutleaf. This useful web app simplifies the creation of clean, professional board pinout reference images.

An undocumented set of low-level commands has been discovered in the ESP32 microchip, a widely used component in IoT devices. Manufactured by the Chinese company Espressif, the ...

After flashing my NodeMCU WROOM32E v1.3 used in combination with the 2.8 TFT SPI 240x320 v1.2 touchscreen I only get a white screen. I tried flashing using the ESPwebtool, FZEE Flasher and using the ...

But this model is powered by a modern, low-power ESP32-S3 processor (with two low-power Xtensa LX7 32-bit microprocessors running at 240 MHz and support for WiFi 4 and Bluetooth 4.2 LE.

Learn about the LittleFS file system and how to use it with ESP8266 NodeMCU to read, write and delete data on flash memory.

In this project, we will check the current consumption of widely popular Wi-Fi and Bluetooth enabled microcontroller unit ESP32 in normal working mode and deep sleep mode.

It looks like ESP32-C3 floodgates have opened. We’ve just written about several NodeMCU ESP32-C3 boards, and now there’s another board with the RISC-V WiFI & Bluetooth processor. Meet LilyGo TTGO T-OI ...

Several "NodeMCU" ESP32-C3 boards with 2.4 GHz WiFi and Bluetooth LE 5.0 have shown up on Aliexpress for around $4 plus shipping.

We can see that the larger antenna footprint will require some thought in PCB design, but otherwise the module has the same pinout as the existing WROVER.

I'd like to wire my DORHEA NodeMCU ESP32 to this TMC2208, but the pinouts are a bit confusing. I'm trying to work off the Simple.ino sketch, and the linked pinout references. I don't see a hardware ...
