HC 08 4 pin Bluetooth Module without Reset Switch

HC 08 4 pin Bluetooth Module without Reset SwitchThe HC-08 BLE module operates using Bluetooth 4.0 protocol and supports UART serial communication, providing an easy wireless link between an MCU (like Arduino, STM32, or ESP32) and a smartphone, tablet, or PC. It features a BLE (Bluetooth Low Energy) interface, which significantly reduces power consumption while maintaining stable, reliable communication — ideal for battery-powered devices.Compared to older modules like the HC-05 and HC-06, the HC-08 offers higher data efficiency, lower latency, and improved range under BLE mode. It functions as a slave device, enabling seamless pairing with smartphones and computers that support BLE.Its onboard PCB antenna ensures excellent wireless performance, while the absence of a baseplate keeps the size and power requirements minimal — suitable for direct soldering into embedded designs.Click here to view the related productsFeatures:-Based on TI CC2540 chipsetBluetooth class 2Industrial level SPP Bluetooth moduleIntegrated chip antennaIndustrial temperature range from -40 to 85Support for on-board applicationsModulation method: GFSKTransfer rate: Asynchronous: 6 KBPS Synchronous: KBPSspecifications:-Frequency2.4GHz ISM.ProtocolBLE 4.0.Bluetooth Version4.0Power supply3.6 V~ 6VMax transmitting powerMax. 4dBm.Modulation SystemGFSK.Serial Baud Rate1200 to 115200 bps.Reference Distance80 meters.Speed1Mbps (Max).Sleep Mode Current0.4uA (MODE 2).Communication PortUART 3.3V TTL.Working temperature-20 ~ 75C.Length (mm)70Width (mm)30Height (mm)10Weight (gm)5ApplicationsWireless communication for Arduino and microcontroller projectsBluetooth-controlled robots and home automation systemsIoT sensors and BLE-enabled devicesRemote control and data logging applicationsSmart wearable devices and low-power electronics*Product image for illustration purposes only, actual product may vary.
