PCB redesign

In Progress

Need a redesign of the open source Open-evse pcb.

Open EVSE project here: [url removed, login to view]

Original pcb design available at this page.

Modification needed:

- Add a max485 (with required components and screw terminals for A/B) for serial rs485 communication with the atmega.

- Add an input for additional Current Transducer for load measurement (with required voltage divider components) and connect as analog input to the atmega.

- Add additional headerpins for digital inputs to atmega for ttl card reader.

Skills: Arduino, PCB Layout
