NXP Semiconductors FRDM-KW36

Overview

FRDM-KW36 from NXP is a Freedom Development Platform built around the KW36Z dual-core ARM Cortex-M0+/M4 Bluetooth Low Energy 5.0 SoC, featuring integrated 2.4 GHz RF transceiver (3.5 dBm output), on-board FXOS8700CQ 6-axis sensor, and OpenSDA debug interface. It supports BLE beaconing, sensor fusion, and wireless connectivity prototyping.

For engineers reviewing the FRDM-KW36 datasheet, FRDM-KW36 pinout, FRDM-KW36 application, or FRDM-KW36 equivalent, this board delivers out-of-box BLE 5.0 demos, integrated sensor data acquisition, USB-powered debug visibility, and FCC/CE/RED-compliant RF validation - critical for rapid IoT endpoint development.

Technical Context

The FRDM-KW36 implements a complete Bluetooth LE 5.0 system-on-module platform with the KW36Z MCU, which integrates dual ARM cores, hardware AES-128 encryption, and a certified BLE stack. It includes an onboard FXOS8700CQ accelerometer/magnetometer and printed PCB antenna compliant with 2360–2483 MHz operation at ≤3.5 dBm.

OpenSDA circuitry provides CMSIS-DAP debug interface over micro-USB, enabling drag-and-drop programming and real-time SWD debugging without external tools. The board supports multiple power sources: USB 5 V, external 9 V via J32, and regulated 1.8 V/3.3 V rails for peripheral interfacing.

FAQ

What is the primary function of the FRDM-KW36?

The FRDM-KW36 is a fully integrated development platform for the KW36Z Bluetooth LE 5.0 SoC. Its primary function is to enable rapid prototyping of secure, low-power wireless applications - including beacons, sensor nodes, and BLE peripherals - with pre-certified RF performance, on-board sensors, and OpenSDA debug capability. The FRDM-KW36 eliminates the need for external debug probes or RF test equipment during early-stage development.

Does the FRDM-KW36 include a certified Bluetooth LE stack?

Yes, the FRDM-KW36 runs NXP's pre-certified Bluetooth LE 5.0 stack on the KW36Z MCU, supporting all core features including advertising extensions, periodic advertising, and long-range mode. This certification covers the RF layer per FCC, CE, and RED requirements, and the FRDM-KW36 ships with out-of-box beacon and sensor demo firmware that leverages the full stack - no additional licensing or stack porting is required for basic BLE functionality.

Can the FRDM-KW36 operate without external power supplies?

Yes, the FRDM-KW36 can operate solely from the micro-USB connection (5 V), which powers the OpenSDA interface, KW36Z MCU, and on-board peripherals including the FXOS8700CQ sensor. No external power supply is needed for standard BLE beacon or sensor demo operation. The J32 9 V input and P5-9V_IN header are optional for higher-current applications or extended peripheral use.

What debug capabilities does the FRDM-KW36 provide?

The FRDM-KW36 features OpenSDA v2.1 - a built-in CMSIS-DAP debug adapter that provides full SWD/JTAG access to the KW36Z MCU over micro-USB. It supports real-time debugging, flash programming via drag-and-drop mass storage, and serial communication through virtual COM port. No external debugger (e.g., J-Link or Segger) is required to develop or validate firmware for the FRDM-KW36.

Is the FRDM-KW36 compliant with radio regulations in Europe and North America?

Yes, the FRDM-KW36 is fully compliant with the Radio Equipment Directive 2014/53/EU (RED) in Europe and FCC Part 15.247 in North America. Its 2360–2483 MHz operation at ≤3.5 dBm output power has been tested and certified. The EU Declaration of Conformity and test reports are publicly available at www.nxp.com/FRDM-KW36, and the FRDM-KW36 carries the CE and FCC ID markings required for legal market access.
