I’ve been working on a number of different aspects of PlainDAQ lately. In particular, I’ve been cost optimizing the PCB, picking components that are easy to source, and working on an intuitive graphical user interface.

Help Me Decide Between Wi-Fi & Bluetooth…

I need change the wireless module, but I need your help to decide between…

  1. An ESP-WROOM-02 Wi-Fi module (first render below)
  2. An HM-BT4502(A) BLE module (second render below)

The PlainDAQ GUI will also provide a number of features for analyzing captured waveforms. And it’s all going to be open-source, so you’ll have the ability to add any additional features you might need.

Lastly, below is a new PlainDAQ logo. It includes a visual that depicts the aliasing effect of sampling and, below that, a list of the board’s basic features:
