- 3.3 V output with up to 6 W of power (taken from V+)
- Support for applying external power to V+, in case PoE is unavailable
- Support for powering via the wESP32-Prog USB port (limited to 5 V on V+)
- Compatible with both PoE Mode A (power over data pairs) and PoE Mode B (power over spare pairs)
-
Connectivity
- High-performance RJ-45 jack with optimized data path has excellent data throughput (iperf UDP scores up to 90 Mbit/s)
- Ethernet auto-MDIX, allowing the use of both straight and cross-over Ethernet cables
- Wi-Fi 802.11 b/g/n is available as a back-up if Ethernet connectivity is unavailable
- Bluetooth v4.2 BR/EDR (basic rate/enhanced data rate) and BLE (Bluetooth low energy)
-
Programming
- Optional wESP32-Prog module for programming
- USB serial console via same wESP32-Prog module
-
Expansion
- 20-pin header footprint with 3.3 V, V+ power, and 15 of the ESP32 GPIOs available for your application
- wESP32-Prog module can be plugged in as needed or permanently soldered
-
Physical Characteristics
- Full data and power path isolation in compliance with the IEEE 802.3at 1500 Vrms isolation requirement
- Compact 75 mm by 40 mm footprint with 4 mounting holes compatible with common M2.5 or 4-40 screws
- High-quality PCB with two oz copper and mounting hole designed to sink heat away from the PoE PD controller for optimal thermal performance
