EZ-BLE51822 Bluetooth Low Energy(BLE) Module has developed by Ezkey Electronics Co.,Ltd. It’s built in Nordic nRF51822 chip to achieve Bluetooth Core Specification for Low Energy-Single Mode Design. Up to date, It can support Nordic Soft Devices S110 or S120 for Slave and Master Mode respectively.
Ezkey provided EZ-BLE51822 without module programming and it’s target for customer own development. If customer require module programming, Firmware Development, Test Jig Development… etc. Please contact for detail.
EZ-51822 provide Ultra Low power Consumption base on it’s Cortex M0 CPU. It can also work with another Proprietary 2.4 HZ concurrently.
1、Cortex M0 chip set, provide Ultra Low Power Platform
2、Support One Chip Solution by using 51822 as Main Controller or work with another MCU since extra hardware requirements…like Scale or Blood Pressure Application…etc.
3、Support UART, SPI, TWI, GPIO...etc.
4、Pins Swap Ability , provide simple layout of Main PCB.
5、Built in 8x 10-bit ADC
6、Support Single Mode “Master”or “Slave”Mode*
7、Support OTA Firmware Upgrade by DFU
EZ-BLE51822 support Nordic Development tools :
nRF51822 EK
J-link LITE by simply connecting 4 pads of module : SWDIO, SWDCLK, VCC, GND
