E18-TBH-01 User manual 1.1
1、Brief introduction
1. Used to test and develop E18 zigbee modules (E18-MS1-PCB, E18-MS1-IPX, E18-MS1PA1-
PCB, E18-MS1PA1-IPX).
2. All IO ports of E18 series have been led out.
3. Designed with CH340G UART chip, UART communication development is available.
4. Designed with USB interface, can connect with your PC directly.
5. User can connect the external power supply and UART directly for secondary development.

Function description：
1.Reset button is for system reset.
2. Double click baud rate rest button is for baud rate rest (default 115200bps)（P1.7）Note: Press the baud
reset button before powering on the new firmware module. Release the button after powering on the new
firmware module.
3.TXD,RXD selection port can used to connect with external UART.
4.Mode selection port: The old firmware is used to switch between AT and HEX instruction modes. When
the jumper cap is inserted, it represents HEX instruction mode (low level), while when the jumper cap is
not inserted, it represents AT instruction mode (high level) (P1.6). Note: The new firmware does not
support AT instruction mode and can be suspended (P1.6).
5. Port ①、②、③、④、⑧、⑨、⑩, and ⑪are used together to test the module current. Without
jumper plugged in for port ①、②、③、④、⑧、⑨、⑩ and ⑪, the galvanometer pen contacts ⑪
ports (above: left positive and right negative), can test the chip current.
