[Introduction]:E49-400T30S is a super cost-effective wireless data transmission module launched by Chengdu Ebyte. It has 4 working modes. Each transmission method has its own characteristics and can be applied to various application scenarios. E49-400T30S can perfectly support industrial-grade applications, and has undergone rigorous testing at the factory to ensure its industrial reliability and batch consistency.
Pin number | Pin name | Pin Orientation | Pin Usage |
---|---|---|---|
1 | GND | Input | Module ground |
2 | VCC | Input | DC Module power positive reference, voltage range: 3.3 ~ 5.5V DC |
3 | AUX | Output | Used to indicate the working state of the module; the user wakes up the external MCU, and outputs a low level during the power-on self-test initialization; (can be left floating) |
4 | TXD | Output | TTL serial output, connected to external RXD input pin; |
5 | RXD | Input | TTL serial port input, connected to the external TXD output pin; |
6 | M1 | Input (very weak pull-up) | Cooperate with M0 to determine the 4 working modes of the module (can not be suspended, if not used, it can be grounded) |
7 | M0 | Input (very weak pull-up) | Cooperate with M1 to determine the 4 working modes of the module (can not be suspended, if not used, it can be grounded) |
11 | ANT | Output | Antenna interface (high frequency signal output, 50 ohm characteristic impedance) |
12 | GND | - | Fixedly |
13 | GND | - | Fixedly |
14 | GND | - | Fixedly |
18~20 | NC | Input/Output | NC pin, this pin needs to be left floating (for subsequent expansion) |
21 | NC | Input | download port --VCC (Hanging, users do not need to pay attention) |
22 | NC | Input | download port –SWDIO (Hanging, users do not need to pay attention) |
23 | GND | Input | download port --GND (Hanging, users do not need to pay attention) |
24 | NC | Input | download port --SWCLK (Hanging, users do not need to pay attention) |
