Wake-up pin

When the cellular module has data to send to the MCU, the wake-up pin on the cellular module will emit a low level for 60 ms by default. The following table lists the default wake-up pin for different module models.

Module model	Default wake-up pin	UART pin	Notes
LZ501CN	Pin 61	UART1	UART2 supports interfacing with Tuya’s GNSS module.
LZ201CN LZ211CN LZ211EAU LZ201EAU	Pin 62	UART1	UART2 supports interfacing with Tuya’s GNSS module.
TCS600U	Pin 70	UART1	UART2 supports interfacing with Tuya’s GNSS module.
MA510GL	Pin 61	UART3	When `UART3_TXD` is high, the device cannot start up. UART2 supports interfacing with Tuya’s GNSS module. UART1 supports AT command. In low power mode, pull down the Pin 41 more than 30ms to wake up the cellular module.
NL668AM	Pin 62	129 (TX), 130 (RX)	-
TCS600E	Pin 20	UART1 (RX17, TX18)	UART2 (RX62, TX67) supports interfacing with Tuya’s GNSS module.
TCS800E	Pin 20	UART1 (RX31, TX32)	UART2 (RX62, TX67) supports interfacing with Tuya’s GNSS module.
MC665EU	Pin 61	UART1 (RX18, TX19)	UART2 (RX39, TX40) supports interfacing with Tuya’s GNSS module.
MG661LA MG661EU MC661CN	Pin 20	MAIN_TXD (18), MAIN_RXD (17)	AUX_UART (RX28, TX29) supports interfacing with Tuya’s GNSS module.
