3 u-blox EVK-BMD-34/38: BMD-345-EVAL
9 The BMD-345-EVALhardware provides support for the u-blox BMD-345
11 ARM Cortex-M4F CPU and Skyworks RFX2411 Front End Module (FEM),
12 also known as a Power Amplifier / Low Noise Amplifier (PA/LNA).
19 * :abbr:`I2C (Inter-Integrated Circuit)`
23 * RADIO (Bluetooth Low Energy and 802.15.4)
27 * :abbr:`UART (Universal asynchronous receiver-transmitter)`

37 More information about the BMD-345-EVAL and BMD-345 module can be
38 found at the `u-blox website`_.
44 The BMD-345 on the BMD-345-EVAL contains an internal high-frequency
45 oscillator at 32MHz. There is also a low frequency (slow)
46 oscillator of 32.768kHz. The BMD-345 does not include the slow
47 crystal; however, the BMD-345-EVAL does.
58 BMD-345 utilizes the Skyworks RFX2411 front end module (FEM).
