These two ESP32 trinkeys *look* similar, but they’re not the same! Yes – both plug into USB A ports, both have reset and user buttons, a NeoPixel and red LED, plus a STEMMA QT I2C port and 3-pin JST SH for analog/digital/PWM. they both contain a CH343P + dual NPN FET for auto-reset circuitry…but one has an ESP32 Pico N8R2 (https://www.digikey.com/short/9ppmnh07) and the other is an ESP32 Mini N4 (https://www.digikey.com/short/31m1drf8). the first module is smaller and contains 8 MB of QSPI flash + 2 MB of PSRAM. The second is larger but only has 4 MB of flash and no PSRAM. why have both? cause the Mini is significantly less expensive, $2.30 vs $3.50, which adds $3 to the final price. For CircuitPython usage, the PSRAM is essential – but for plain C/C++ development, you can get away with skipping. either way, these could be handy little boards for creating sensor nodes that plug into a wall outlet, with easy extensibility for I2C or analog/digital/PWM I/O!
