E32-433T30D is a wirel ess transceiver module based on SX1278 from SEMTECH(can be transmitter and receiver both). It adopts LoRa spread spectrum technology, with this technology the transmitting distance and penetration ability of the module improved more than 1 times compared with traditional FSK.The module features FEC (forward error correction) algorithm, which ensure it's good anti-interference ability. E32-433T30D can be compatible with other E32 modules.

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
