[Introduction]：E49-400T30D 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. E49-400T30D 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 | 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) |
| 2 | 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) |
| 3 | RXD | Input | TTL serial port input, connected to the external TXD output pin; Can be configured as open-drain or pull-up input, see parameter settings for details. |
| 4 | TXD | Output | TTL serial output, connected to external RXD input pin; Can be configured as open-drain or push-pull output, see parameter settings for details. |
| 5 | AUX | Output | It is 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; it can be configured as open-drain output or push-pull output, see parameter settings for details. (can be left floating) |
| 6 | VCC | Input | DC Module power positive reference, voltage range: 2.6 ~ 5.5V DC |
| 7 | GND | Input | Module ground |
| 8~11 | Fixing hole | - | Fixing hole |
