## Description

The BMD-34 series is a compact, surface-mount multiprotocol RF module for low-power embedded designs needing Bluetooth 5, Thread or Zigbee connectivity at 2.4 GHz. It is based on the Nordic nRF52840 and combines an Arm Cortex-M4 with FPU, integrated radio and hardware cryptographic engine in a ready-to-integrate module.It breaks out a broad set of interfaces including ADC, GPIO, I²C, I²S, PDM, PWM, SPI, UART and USB, making it suitable for connected sensors, portable devices and demanding wireless control applications. The module uses a U.FL antenna connection, with the antenna not included.Built-in USB and a 5.5 V compatible DC-DC supply help reduce design complexity and BOM cost. The module family is certified for Europe, US, Canada, and Australia/New Zealand.Specifications:RF Family/Standard: 802.15.4, BluetoothProtocol: Bluetooth v5.0, Thread, Zigbee®Frequency: 2.4GHzData Rate: 1MbpsPower - Output: 18dBmSensitivity: -102dBmSerial Interfaces: ADC, GPIO, I²C, I²S, PDM, PWM, SPI, UART, USBAntenna Type: Antenna Not Included, U.FLUtilized IC / Part: nRF52840Memory Size: 1MB Flash, 256kB RAMVoltage - Supply: 2V ~ 3.6VCurrent - Transmitting: 4.8mAMounting Type: Surface MountOperating Temperature: -40°C ~ 85°CA solid choice for engineers building compact wireless products that need Bluetooth, 802.15.4 networking, long range capability and access to the nRF52840 peripheral set.
