Seeed BLE Shield Bluetooth Expansion Board Compatible with Arduino Seeeduino for DIY
Description:
It is based on the cc2541 TI chip BLE module, very suitable for ultra low power system. Built in powerful network node. The module is small in size and easy to use. You can quickly build BLE communication via its AT command . Support communication with iPhone, iPad and BLE Android4.3.
Specification:
- Bluetooth protocol: BluetoothV4.0 BLE
- Operating frequency: 2.4GHz ISM frequency band
- Interface mode: serial port
- 30 meters, open environment, can realize the communication between the modules,send and receive modules without byte limit
- Modulation: GFSK
- Transmit power: DBM, - 23-6 DBM, 0dBm, 6 dBm, can modify by AT command
- Using Ti cc2541 chip, 256Kb configuration space, support AT command, the user can change equipment (the main/slave mode), and the serial baud rate, name, parameter matching, such as passwords.
- Power supply: DC +3.3V 50mA
- Operating temperature: - 5~65deg C
Package included:
- 1 x BLE Shield
- 1 x Arduino source code
- 1 x Schematic diagram
- 1 x Chip datasheet
