E18-MS1-PCB is based on the original imported RF chip CC2530 from TI in America. The IC chip is integrated with an 8051 microcontroller and wireless transceiver inside, which applies to Zigbee design and 2.4GHz IEEE 802.15.4 protocol. All the IO ports are led out by the module, which means that multi-aspect development is realizable. E18-MS1-PCB provides an easy and cost-effective way to upgrade existing systems with 2.4GHz Zigbee capabilities. It ensures the high performance of your designs with reliable data transmission and reception.

Pin parameters
| Pin number | CC2530 Pin name | Module Pin name | Input/Output | Pin usage |
| 1 | GND | GND | Ground wire, connected to the power reference ground | |
| 2 | VCC | VCC | Power supply, must be between 1.8' 3. 6V | |
| 3 | P2.2 | GPIO | I/O | DC-download program or Debug clock interface |
| 4 | P2. 1 | GPIO | I/O | DD-download program or Debug data interface |
| 5 | P2.0 | GPIO | I/O | N/C |
| 6 | Pl. 7 | NWK_KEY | I | Used for manual join, exit, and quick match keys. Not networked: Short press to join the network or create a network operation; Networked: Short press for quick match; Long press means to leave the current network; Note: Low level is valid, 100ms W short press W 3000ms, 5000 W long press. |
| 7 | PL 6 | GPIO | I/O | N/C |
| 8 | NC | NC | N/C | |
| 9 | NC | NC | N/C | |
| 10 | Pl. 5 | UARTO.TX | I | Serial port TX pin |
| 11 | Pl. 4 | UART0_RX | 0 | Serial port RX pin |
| 12 | Pl. 3 | RUN_LED | 0 | It is used to indicate the network access status of the module. Fast flashing 256 times (10Hz frequency) indicates that it is joining the network or creating a network, and slow flashing 12 times (2Hz frequency) indicates that the module has joined the network or successfully created the network; Low level lights up; |
| 13 | Pl. 2 | NWK_LED | 0 | It is used to indicate the one key pairing status of the module, provided that two modules need to join the same coordinator, and then one key pairing can be performed. In the transparent mode, mutual transparent transmission can be performed. Low level lighting; |
| 14 | Pl. 1 | GPIO | I/O | The PA transmit control pin has been connected inside the module; There is no PA inside the E18-MS1-PCB/E18-MS1-IPX; |
| 15 | P1.0 | GPIO | I/O | The PA receiving control pin has been connected inside the module; There is no PA inside the E18-MS1-PCB/E18-MS1-IPX; |
| 16 | P0.7 | HGM | 0 | HGM pin of PA; E18-MS1-PCB/E18-MS1-IPX has no PA inside, so this pin is used as GPIO port; |
