A ~$30 bench rig — an Arduino Uno R3 plus two MCP4725 DACs — that answers one question about a MOSFET: is it viable for cascaded digital logic? It sweeps gate and drain voltages and reports gate ...
WARNING: Since the IoT RedBoard with ESP32 has a system voltage of 3.3V, the logic levels is 3.3V instead of 5V on the RedBoard with ATmega328P. Thus, the analog reference voltage for the ...
