| + | ====== JetHome Zigbee module ZB4C v.1 (EFR32MG21) ====== | ||
| + | |||
| + | The module is designed to work as a Zigbee coordinator or end device as part of a Smart Home controller with the appropriate software installed and configured. | ||
| + | |||
| + | The module is based on a modern Silicon Labs EFR32MG21A020F1024IM32 wireless microcontroller for the 2.4GHz band and features high performance, | ||
| + | |||
| + | Main technical characteristics: | ||
| + | |||
| + | * 80МГц | ||
| + | * Flash memory 1024KB; | ||
| + | * SRAM 96KB; | ||
| + | * Transmitter output power up to +20 dBm; | ||
| + | * Supply voltage 3.3V; | ||
| + | * Current consumption in active mode up to 200 mА. | ||
| + | * Overall dimensions of the module 28 х 18 mm. | ||
| + | |||
| + | The module is based on the schematics of the Silabs EFR32xG21 (BRD4180B) debug board based on the EFR32MG21 chip: | ||

| + | ===== Supported firmware ===== | ||
| + | |||
| + | For information on supported firmware, see the documentation: | ||
| + | |||
| + | When using firmware from USB stick Z4: | ||
| + | * Provides a transition to the bootloader mode at a low logic level at the input PB00. | ||
| + | * It is possible to connect LEDs to indicate the operating mode: PD02 (red LED) and PD03 (green LED). A high logic level on these pins lights the corresponding LED. | ||
| + | * The UART TX line is output to PA05, UART RX - PA06. Hardware flow control RTS/CTS is not used. | ||
| + | |||
| + | ===== Module flashing procedure ===== | ||
