[Introduction]：EWM220M-400T22S is a new generation of LoRa wireless serial port module (UART). It has multiple transmission modes, works in the 410.125~493.125MHz frequency band (default 433.125MHz), LoRa spread spectrum technology, TTL level output, and is compatible with 3.3V and 5V IO port voltages. The LoRa module has long transmission distance, fast speed, low power consumption, small size, and high cost performance; it supports air wake-up, carrier monitoring, communication key and other functions, supports sub-packet length setting, and can provide customized development services. This product can cover an ultra-wide frequency range of 410~493MHz.

3 GND - Module ground wire
4 GND - Module ground wire
5 TX_EN Output Used with RX_EN to control external PA; left unconnected if not used
6 RX_EN Output Used with TX_EN to control external PA; left unconnected if not used
7 CLK Input/Output SWCLK Clock pin when program is loaded (suspended, user does not need to connect)
8 PART Input/Output SWDIO data pin when program is loaded (suspended, user does not need to connect)
9 NC - Empty foot (not open for use, users do not need to care)
10 NC - Empty foot (not open for use, users do not need to care)
11 NC - Empty foot (not open for use, users do not need to care)
12 NC - Empty foot (not open for use, users do not need to care)
13 GND - Module ground wire
14 VCC - Module power positive reference, voltage range: 2.7～5.5V DC
15 TXD Output TTL serial port output, connected to the external RXD output pin;
16 RXD enter TTL serial port input, connected to external TXD output pin;
17 M1 enter Cooperate with M0 to determine the 4 working modes of the module ( cannot be left floating , can be grounded if not used)
18 M0 enter Cooperate with M1 to determine the 4 working modes of the module ( cannot be left floating , can be grounded if not used)
19 TO Output Used to indicate the working status of the module; the user wakes up the external MCU, and outputs a low level during the power-on self-test initialization period; (can be left floating)
20 NC - Empty foot (not open for use, users do not need to care)
21 RESET enter Module reset pin, low level reset.
22 GND - Module ground wire
23 ON - Antenna interface (high frequency signal output, 50 ohm characteristic impedance)
24 GND - Module ground wire
