[Introduction]:E22-900T30D is a wireless module (UART) based on SEMTECH's LoRa solution. It has multiple transmission modes and works at 850.125MHz~930.125MHz (default 868.125MHz). Adopting LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage.
Name | Direction | Function |
MO | Input (weak pull-up) | Work with Ml to decide 4 working modes of module (not suspended, if not used, could be grounded). |
Ml | Input (weak pull-up) | Work with MO to decide 4 working modes of module (not suspended, if not used, could be grounded). |
RXD | Input | TTL UART inputs, connects to external (MCU,PC) TXD output pin. Can be configured as open-drain or pull-up input. |
TXD | Output | TTL UART outputs, connects to external RXD (MCU, PC) input pin. Can be configured as open-drain or push-pull output |
AUX | Output | To indicate module ' s working status & wakes up the external MCU. During the procedure of self-check initialization, the pin outputs low level. Can be configured as push-pull output (suspending is allowed). |
VCC | Input | Power supply : 3.3~5.5VDC |
GND | Input | Ground |
Fixed hole | - | Connect to GND |
