    ESP32-POE is OSHW certified Open Source Hardware with UID BG000009 ESP32-PoE is an IoT WIFI/BLE/Ethernet development board with Power-Over-Ethernet feature. The PoE is handled by Si3402-B chip that is IEEE 802.3-compliant, including pre-standard (legacy) PoE support. The PoE powering requires at least 37V DC to operate successfully. I use the RMT (Remote Control) devices of the ESP32 from FreeRTOS for this. They were intended for generating on-off-keying of carrier modulated wave forms to blink an IR LED for a remote control. If you leave off the carrier modulation you end up just specifying a list of on and off times and get absolutely rock solid waveforms in hardware. M5StickC is a ESP32 development board with 0.96 inch TFT color screen (80 * 160 resolution), Red LED, button, Microphone, IR transmitter, 6-axis IMU (SH200Q) and 80 mAH battery.
