AP_Periph CAN Battery Monitor

I’m looking for an embedded-systems engineer who can take ArduPilot’s AP_Periph codebase and turn it into a robust CAN-bus battery monitor. The unit will sit on a DroneCAN network and stream full MAVLink telemetry, so it can slot straight into my existing ground-station setup without any extra protocol bridges. Integration with other telemetry options such as S.Bus or SmartPort isn’t needed right now.

Key functions I must see on the bus:
• High-accuracy individual cell voltage for every cell in the pack (not just pack voltage)
• Hall-effect current sensing that stays linear and low-loss all the way to 400 A
• Standard AP_Periph health, identification and parameter handling so the flight controller recognises the device instantly

Deliverables
1. Schematic and PCB GERBER/assembly files ready for production
2. Bill of materials with sourcing notes for the hall sensor and any precision ADC components
3. Customised AP_Periph firmware (.hex plus source) with clear documentation on parameter layout and MAVLink message mapping
4. Bench-test report demonstrating cell-voltage accuracy and current-sense linearity up to 400 A (simulated loads are fine)
5. Quick-start guide so I can flash, connect and see data flowing in Mission Planner the first time I power up
6. similar to https://wiki.cbunmanned.com/wiki/products/2-8s-battery-monitor

I have a test rig ready and can provide live feedback during development. Let me know how you plan to tackle the high-current measurement and any previous DroneCAN or AP_Periph projects you’ve handled, and we can get moving.
