Multi-purpose Battery Manager – I/O Expander module PCB (August 2022)

PCB for the Multi-purpose Battery Manager project in the August 2022 issues of PE.

Our recent Battery Multi Logger is a great tool for monitoring and diagnosing battery problems. But sometimes, you need something which will not just monitor what’s going on but also take action, such as connecting and disconnecting loads based on battery charge state. That’s just part of what this Battery Manager does.

This is the I/O Expander module PCB, the Switch Module PCB is available HERE

Please note this PCB is supplied without components.
