PurpleDrop 6.0
This version is not recommended for use. Rev 6.1 has all the same features, but fixes several bugs in Rev 6.0 that require substantial re-work.
This version updates the PurpleDrop board to use an STM32F413 microcontroller. It adds:
- USB peripheral for control and power
- Electrode capacitance sensing
- Adds a fourth RTD temperature sense amplifier
- Software controlled high voltage setting
