ESP-POE-ZB-v1.2

ESP32 POE: ZigBee + BLE gateway

Features:

• ESPHome compatible,
• ESP32-S (with U.FL connector) used as BLE receiver, main gateway controller,
• Ebyte E72-2G4M20S1E (CC2652p with U.FL connector) as ZigBee coordinator,
• POE 802.3af/802.3at (36-57 VDC) with LAN8720,
• passive POE 12-57V (experimental, need to solder jumper on PCB),
• USBC for flashing, based on CH340C (can be used for powering),
• power connector: 10-57 VDC (abs max 70V - needs to replace capacitor),
• external connectors: 3xGPIO (internal pulled up, for SCL, SDA, 1Wire), 3.3V, 5V, GND,
• internal connectors: SCL, SDA, 3.3V, GND (SCL and SDA shared with external connector; more gpio available without zigbee module),
• compatibile with Kradex Z102 enclosure for din rail,
• support for RS485/MODBUS (need to add ISL83485 or similar - note: RS485 disable I2C and 1Wire),
• BUS (input/POE) voltage monitoring,
• LEDs: power (green) and status (amber).

DO NOT POWER ON MODULE WITHOUT ANTENNAS
