Both HM-17 and HM-19 use TI's CC2640R2F chip, the hardware circuit is the same, but the firmware protocol part of the programming is different, HM-17 is BLE (4.2) protocol,HM-19 is BLE (5.0) protocol.

The size of the two modules is 13*18* 2mm. The module has the characteristics of fast speed, small size and low power consumption. The pins are compatible with HM-06, HM-11, HM-13. No need to change the hardware circuit, just replace it directly , The use is simple, convenient and fast.
