I've just received five ESP32 modules and have two or three spare. Does anybody want one for $10 - you can pick up from me in Durham St South.<br>
<br>
Looks exactly like in the pictures at <a href="https://www.aliexpress.com/item/ESP-32-ESP-32S-Wireless-WiFi-Bluetooth-Development-Board-2-4GHz-Micro-USB-CP2102-Dual-Core/32800542320.html" rel="noreferrer" target="_blank">https://www.aliexpress.com/ite<wbr>m/ESP-32-ESP-32S-Wireless-WiFi<wbr>-Bluetooth-Development-Board-<wbr>2-4GHz-Micro-USB-CP2102-Dual-<wbr>Core/32800542320.html</a><br>

For those not familiar with these modules, they are 240 MHz dual-core microcontrollerswith 520 KB SRAM and 4MB of flash, Integrated 802.11 b/g/n HT40 Wi-Fi transceiver, and dual mode Bluetooth.You can program for either the ESP IDF framework (at <a href="https://github.com/espressif/esp-idf" rel="noreferrer" target="_blank">https://github.com/espressif/e<wbr>sp-idf</a>), or play around with the Arduino support (available at <a href="https://github.com/espressif/arduino-esp32" rel="noreferrer" target="_blank">https://github.com/espressif/a<wbr>rduino-esp32</a>). As usual, everything works easier on Linux.The 3.3V Power usage is about 150mA with Wifi running, 50mA with the WIfi shut down, and 2.4mA when the CPU is in deep sleep - most of which is the carrier board. as the actual ESP32 module is 2.4uA when in deep sleep!<br>
