Ebyte E180-ZG120B-TB specifications:
- Zigbee Module – Ebyte E180-ZG120B powered by Silabs EFR32MG1B Arm Cortex-M4 @ 40 MHz with 256 KB flash, 32KB SRAM; IPEX antenna connector; dimensions: 18 x 11.5mm
- Connectivity
- 2.4GHz Zigbee 3.0 & Thread
- Tx Power: 18 to 20dBm
- Range up to 1.3 km
- USB – 1x Micro USB port for power and programming via CP2102G serial chip
- Expansion
- 2x 14-pin headers plus 9-pin header giving access to module I/Os including GPIO, UART, PWM, ADC, TouchLink, Wake, RESET, DBG, 3.3V, and GND
- 6-pin header for power, 1x UART for CP2102G, 1x UART for module; Fitted with 3 jumpers by default to connect both Tx/Rx, as well as 3.3V power pins. Removing the jumper should allow you to connect directly to the module, and/or power it with your own 3.3V supply instead of relying on the built-in LDO.
- Misc – 4x buttons: Baud rate reset, mode change, touch link, and “some Chinese characters”
- Power Supply – 5V via USB port (3.3V LDO output), 3.3V via header
- Dimensions – 55x30mm
There’s little information about the firmware in the product pages for the module and test kit, although it’s supposed to be compatible with ZHA & ZLL (TouchLink) protocols, but a commenter in Github mentions it’s using a proprietary firmware:
Ebyte E180-ZG120A(B) is a Serial port transparent transmission module, running Ebyte private firmware,not EZSP. (However, it can act as a standard ZigBee3.0 router in the Network)
…
… the moudule (sic) running a Ebyte offical firmware cant’t act as a standard coordinator like CC2652R, while it can connect your serial device to ZigBee network easily.
EZSP refers to Silicon Labs’ “EmberZNet Serial Protocol“. The comment was made to answer a request to add support for Silicon Labs EFR32MG1 Series 1 Module, including Ebyte module and evaluation kit, to zigbee-herdsman open-source ZigBee gateway solution into order to eventually get support into zigbee2mqtt and/or Home Assistant’s ZHA. But based on comments in this thread, it’s not trivial and unlikely to happen.
If you’d like to give the board a try, Ebyte E180-ZG120B-TB is sold for around $9 on Aliexpress and a bit more on eBay UK. The module itself is sold for $6.88, and there’s also an “RS232 ZigBee3.0 Serial Data Transparent Transceiver” with a case, antenna connector, and serial terminal block sold for $23.24 including shipping..
