With 256KB Flash, 32KB ROM, and 24KB SRAM, it provides ample resources for custom BLE application development. The module supports UART, SPI, and I2C host interfaces, and features 18 GPIO, 8-channel 12-bit ADC, 3 PWM outputs, and a temperature sensor. Pre-certified for FCC, IC, CE, and TELEC, it significantly reduces time-to-market for wireless products.","working_principle":"The BM70BLES1FC2-0B03AA integrates a complete BLE radio subsystem and protocol stack. **Radio Subsystem**: The 2.4GHz transceiver supports Bluetooth 5.0 with GFSK modulation. The integrated ceramic chip antenna provides omnidirectional radiation, and the onboard RF shield minimizes interference. TX power up to +2 dBm and RX sensitivity of -90 dBm deliver reliable communication over 10-30m range. **Protocol Stack**: The complete BLE 5.0 protocol stack runs from internal ROM\/Flash, including Link Layer, L2CAP, ATT, GATT, SMP, and GAP. LE Secure Connections (AES128) provide secure pairing. **Host Interface**: The UART interface (9600-115200 baud) provides a simple serial command interface to the host MCU. SPI and I2C interfaces are also available for higher data rate applications. **Power Management**: Deep sleep mode draws only 2.9 uA while maintaining connection state. Buck mode reduces active current to 3.87mA TX and 3.06mA RX at 3.0V supply. **ADC Subsystem**: The 12-bit ADC with 8 input channels and battery voltage detection enables sensor measurement without an external MCU.","pin_description":"
