Background
A Printed Circuit Board (PCB) has been designed and manufactured. The goals were to make it quicker and easier to build a system and to make it more reliable, to establish a relationship with a board house and to test the layout of the RJ connectors and mating with the Pi. This is an interim solution - a step towards the goal of a complete turnkey system.
- All sensor plug in.
- 12 VDC power supply with battery voltage monitoring
Problems
ADC is only one channel. No RTC Board does not meet Pi HAT spec
Proposed change
Split this board in two.
- One board will meet the Pi HAT specifications and contain:
- at least one 4 channel ADC so each load cell will be individually measured instead of being summed.
- Real Time Clock with battery backup.
- Configuration ROM
- One board will have all the connectors installed in a bulkhead configuration.
