TTL & RS232 Typical Application
Figure 3 .HM-TRP TTL UART Application
In Figure 3, connect the DTX pin of HM-TRP with UART RX Pin of MCU, connect the DRX pin of HM-TRP
with the UART TX pin of MCU. Then the CONFIG & ENABLE of HM-TRP connects with the GPIO of MCU,
thus the minimal application of TTL is set up.
Figure 4. HM-TRP extends to RS232 application
In Figure 4, you can extend the HM-TRP to RS232 with adding the MAX3232, then you can directly connect the
COM to the PC.
