PlainDAQ is a module that turns your Raspberry Pi Pico into a simple, precision 4-channel oscilloscope and a single channel function generator. Optionally it can also include a Wi-Fi module to add wireless capability to Raspberry Pi Pico modules.
To put it other words, PlainDAQ is a simple, useful tool to add basic precision analog functionality to your Raspberry Pi Pico board. It has a precision, low-noise, low-drift 12-bit 500kSPS/s ADC, sampling 4-channels and supporting 3 ranges (±1V, ±2V, ±4V). It also has a 10-bit DAC which helps create analog outputs and waveforms and it has a single range of ±4V.
