PlainDAQ: DAQ module for Raspberry Pi Pico

Alperen a Hardware Engineer from Kuncu Teknoloji, Turkey has built PlainDAQ, open source DAQ adapter board for Raspberry Pi PICO.

It has a precision, low-noise, low-drift 12-bit 500k sps/s ADC (Microchip MCP33151). To reduce noise and maintain precision, all analog inputs are buffered and driven with high-speed/low-noise differential amplifier.

It also has one channel 10-bit DAC which helps create analog outputs or even waveforms as it can output 50 k samples per second with a range of +-4V.

PlainDAQ generates ±5 V voltages to offer bipolar power supply, which is a bit of a challenge to generate.

PlainDAQ includes a precision voltage reference with 20 ppm/°C drift. Each PlainDAQ is calibrated with DMM7510 before shipment and later when in use, can be calibrated with proper equipment and calibration data could be store in the EEPROM present on the board.

PlainDAQ will also come with an option of BLE connectivity for capturing the data which makes it easy to implement wireless dataloggers, temperature loggers or any parameter monitoring solution.

PlainDAQ is launched on Crowd Supply and will be ready to be backed soon. You can subscribe for the updates.

Some documentation is available on GitHub and more will be shared once the product is live on Crowd Supply.
