[Introduction]：Le module E290-400T30S est un module sans fil de nouvelle génération, un module de port série sans fil UART basé sur la puce RF PAN3060 de Panqi Micro. Il dispose de plusieurs modes de transmission, fonctionne dans la bande de fréquences (410,125 à 493,125 MHz), adopte la technologie à spectre étalé ChirpIoT™ et dispose d'une sortie de niveau TTL.
Magasin officiel
| Pin number | Pin name | Pin Direction | Pin usage |
| 1 | GND | Input | Module ground wire |
| 2 | VCC | Input | Module power supply positive reference, voltage range: 3.3~5.5V DC |
| 3 | TO | Output | Used to indicate the working status of the module; the user wakes up the external MCU, and outputs a low level during power-on self-test initialization; (can be suspended) |
| 4 | TXD | Output | TTL serial port output, connected to the external RXD input pin; |
| 5 | RXD | Input | TTL serial port input, connected to the external TXD output pin; |
| 6 | M1 | Input (extremely weak pull-up) | Cooperate with M0 to determine the 4 working modes of the module (not suspended, if not used, grounded) |
| 7 | M0 | Input (extremely weak pull-up) | Cooperate with M1 to determine the 4 working modes of the module (not suspended, if not used, grounded) |
| 11 | On | Output | Antenna interface (high frequency signal output, 50 ohm characteristic impedance) |
| 12 | GND | - | Fixed |
| 13 | GND | - | Fixed |
| 14 | GND | - | Fixed |
| 18 | NC | - | SWCLK Clock pin when the program is loaded (dangled, no need for user connection) |
| 19 | NC | - | Data pins when SWDIO program loads (dangled, no need for users to connect) |
| 20 | NC | - | GPIO/RS485_en |
| twenty one | NC | - | MCU_VDD The power pin of the program download (dangling, user does not need to connect) |
| twenty two | RESET | Input | Module reset foot |
| twenty three | GND | Input | Fixed |
| twenty four | NC | - | Empty feet |
