Figure 2. FRDM-KW36 Freedom development board
The FRDM KW36 development board includes these features:
• NXP ultra-low-power KW36A Wireless MCU supporting Bluetooth LE and Generic FSK.
• Compliant Bluetooth 5 LE.
• Reference design area with small-footprint, low-cost RF node:
— Single-ended input/output port.
— Low count of external components.
— Programmable output power from -30 dBm to +3.5 dBm at the SMA connector, when using DCDC Bypass or
operating the DCDC in Buck mode.
— Receiver sensitivity is -100 dBm, typical (@1 % PER for 20-byte payload packet) for GFSK applications (250 kbps,
BT=0.5, h=0.5), at the SMA connector.
— Receiver sensitivity is -95 dBm (for Bluetooth LE applications) at the SMA connector.
• Integrated PCB inverted F-type antenna and SMA RF port (requires moving C55 to C57)
• Selectable power sources.
• DC-DC converter with Buck, and Bypass operation modes.
• 32 MHz reference oscillator for RF operation.
• 32.768 kHz reference oscillator mainly used for RTC operation and RF low power operation.
• 2.4 GHz frequency operation (ISM and MBAN).
• 4-Mbit (512 kB) external serial flash memory for Over-The-Air Programming (OTAP) support
• NXP FXOS8700CQ Digital Sensor, 3D Accelerometer (±2g/±4g/±8g) + 3D Magnetometer
• Thermistor circuit to test KW36 ADC module.
• Coin cell connector compatible with a CR2032 coin cell. CAN/LIN transceivers are not functional when using coin cell.
