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.
- 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.
Hi, I take a look at the projetct page, and the project seems to be done using eagle. I may need to redraw averything to avoid eagle size limitation of eagle free version.
