Parameters
Typical Application
HM-TRLR-S TTL UART
As in the above Figure, connect the TXD pin of HM-TRLR-S with UART RXD Pin of MCU, connect the RXD pin of HM- TRLR-S with the UART TXD pin of MCU. Then the CONFIG/SLEEP/RESET/STATUS of HM-TRLR-S connects with GPIO of MCU.
HM-TRLR-S extends to RS232
You can extend the HM-TRLR-S to RS232 by adding the MAX3232, and then you can directly connect the COM to the PC.
