Capacitive Keypad and RFID for OpenEVSE: Hardware
A professional 4-channel RF RCA switching system with specialized RX (114.475mm x 72.575mm) and TX (71.475mm x 70.575mm) units. Features Omron G5V-1 relays, Right-Angle RCA jacks, and MCP1640 boost converters for stable 5V operation from AA batteries. Designed in KiCad v10.0 with optimized bottom-layer component placement
Based on https://www.instructables.com/DIY-1kW-MPPT-Solar-Charge-Controller/ Since I wanted to be able to change the board layout and to test KiCad I decided to give this "conversion" a try.
A simple PCB design that detects low battery levels using a high-voltage divider and triggers a buzzer via a 5 V DC-DC module. Includes input filtering, surge protection (TVS), and transistor-based threshold switching. KiCad project + BOM + gerbers.
