[Introduction]:This module features FEC(forward error correction) algorithm, and it can work at WOR (wake-up on radio), which is perfectly suitable for ultra-low power consumption applications. E30-433T20S can be compatible with other E30 modules.

E30-433T20S
Pin No. Pin Item Pin Direction Pin Application
1 M0 Input(weak pull-up) Work with M1 & decide the four operating modes. (Floating is not allowed, can be ground)
2 M1 Input(weak pull-up) Work with M0 & decide the four operating modes. (Floating is not allowed, can be ground)
3 RXD Input TTL UART inputs, connects to external (MCU, PC) TXD output pin.Can be configured as open-drain or pull-up input.
4 TXD Output TTL UART outputs, connects to external RXD (MCU,PC) input pin.Can be configured as open-drain or push-pull output
5 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 open-drain output or push-pull output. (Floating is allowed)
6 VCC Input Power supply 2.3V~5.5V DC
7 GND Input Ground electrode
8 ANT Output Antenna interface( high frequency signal output)
9 GND Output Reference places of high frequency signal output
10 GND Input Ground electrode
11 GND Input Ground electrode
