HM 19 Bluetooth Module

The HM-19 is an upgraded model of the HM-11.

The HM-19 makes use of TI’s CC2640R2F chip because the grasp IC.

In comparison with HM-11, HM-19 is a Bluetooth 5.0 BLE module,it has a sooner switch fee and a bigger MTU.

This module can be utilized not just for DIY undertaking, but additionally in your merchandise.

Authentic HM-19 module, DSD TECH model ensures and that we settle for refund with none excuse..
Bluetooth 5.0 BLE Module: essentially the most IC is CC2640R2F from TI,In comparison with the Bluetooth 4.0 module, this module incorporates a sooner switch fee and a much bigger MTU.

DSD TECH 6 PIN base Board: ends in VCC, GND, TX, RX,STATE,EN. You may be very handy to connect to your arduino undertaking or different DIY undertaking.

DSD TECH provides a free app that means that you can rapidly combine this module into your undertaking.Please search “DSD TECH Bluetooth” in Google Play and due to this fact the Appstore.

The HM-19 is an upgraded model of the HM-11. The HM-19 makes use of TI’s CC2640R2F chip as a result of the grasp IC.

This module are sometimes used not only for DIY undertaking, but additionally in your merchandise.
Its Work voltage(VCC): 3.6V to 6V and TTL logic stage (TX, RX): 3.3V, Helps Bluetooth protocol: 5.0 BLE and Chip: TI CC2640R2F. Its fundamental mode helps two working modes: automated working and guide working.

The AT instructions of the HM-19 module are appropriate with the AT instructions of the HM-11 and HM-10 module.

HM-19 Bluetooth 5.0 Clear interface Grasp-Slave Module CC2640 MCU Hello Pace appropriate with HM-11 HM-13 HM-17.

DSD TECH again this HM-19 Bluetooth 5.0 BLE module with ONE Yr WARRANTY and lifelong technical assist.

The sooner hm-19 present model V103 helps the following options:
Transmission mode, transmission + distant twin operation mode.The primary mode helps automated work and guide work.Extremely-high transmission velocity (BLE as much as 8KB/S). Considerable AT instruction, supporting native serial AT instruction and distant AT instruction and Tremendous MTU 253Bytes. It Help iBeaon operate and firmware improve.

It’s included with 4.2 and 5.0, default 2M bandwidth connection, appropriate with 1M bandwidth.
