ZcoRE3-2400_User_Manual_V1.0
The pin definition of the header interface is shown on Table 3.1; the input and output description is
based on module side. The main serial port is port 1 which includes TxD1 (pin 5) and RxD1 (pin
7). It will be set as the default port in the factory. There are three UART ports which can be used
on the module.
Pin 3 (RST) is the reset input; the module will reset if a low level signal is input.
The ZcoRE3-2400/ZcoRE3(20)-2400 module provides RFD two power modes, wakeup and sleep
mode. In wakeup mode, the module can execute normal operations, transmit and receive data via
the RF channel. A low level input on Pin 19 will put the RFD module enter sleep mode.
Pin 17, 28 and 30 can be used for temperature or battery voltage detecting input.
Pins 27, 32, 34, 36, 38 are reserved for In-System Programming (ISP), and also for firmware
debugging. All these pins are dedicated to JTAG and cannot be used for any other IO functions.
