Summary MeshCam is an ESP32-based wildlife camera network that transfers motion-triggered images through a low-bandwidth LoRa mesh and forwards them to a self-hosted server through an internet-connected gateway. The current wired gateway uses an ESP32-WROOM board with a LAN8720 RMII Ethernet PHY and Power over Ethernet. This project does not currently use WIZnet products. A WIZnet W5500 could replace the existing RMII Ethernet path in a custom gateway by providing SPI-connected Ethernet with hardware-managed TCP/IP sockets, but that change would require adapting the firmware’s UDP, HTTPS…
