Telegesis Legacy Modules

Telegesis modules are low-power 2.4 GHz ISM band transceivers based on EM35x single chip Zigbee / IEEE 802.15.4 solutions. The unique AT-style command line interface allows developers to quickly integrate meshing radio technology.

Due to the evolution of the Zigbee and Thread (OpenThread) protocols, Flash and RAM requirements have increased. We recommend migrating to an EFR32MG based module with more Flash and memory to future proof designs:

  • MGM12P for Zigbee, Thread and multiprotocol applications
  • MGM210P for mains powered mesh applications including lighting, gateways and voice assistants
