Texas Instruments CC2541DK-SENSOR

Overview

CC2541DK-SENSOR from Texas Instruments is a Bluetooth Low Energy (BLE) sensor development kit built around the CC2541 SoC, integrating six calibrated sensors (IR temperature, humidity, pressure, accelerometer, gyroscope, magnetometer), an onboard PCB antenna, and CR2032 battery power - enabling rapid smartphone app prototyping for BLE sensor applications without embedded firmware development.

For engineers reviewing the CC2541DK-SENSOR datasheet, CC2541DK-SENSOR pinout, CC2541DK-SENSOR application, or CC2541DK-SENSOR equivalent, this kit serves as a validated reference platform for BLE 4.0 peripheral design, sensor fusion evaluation, iOS app integration, and TI BLE stack v1.30+ interoperability testing - with FCC/IC/TELEC regulatory certification for the RF board.

Technical Context

The CC2541DK-SENSOR implements a complete Bluetooth Smart (BLE 4.0) peripheral node using the CC2541 System-on-Chip, which integrates a 2.4 GHz RF transceiver, 8051 MCU core, and BLE protocol stack. All six sensors interface via I²C with individual enable control to minimize active current draw.

Sensor data acquisition is managed by firmware that places unused sensors in sleep mode between measurements; the side button controls advertising state and powers the D1 LED indicator. The kit operates at 3.0 V nominal from the CR2032 battery and complies with ETSI/R&TTE over 0–35°C ambient.

FAQ

What is the primary function of the CC2541DK-SENSOR?

The CC2541DK-SENSOR is an evaluation kit that functions as a ready-to-use Bluetooth Low Energy sensor node. It enables rapid development of iOS apps for BLE accessories by providing calibrated sensor data over standard BLE GATT services - eliminating the need for custom firmware or hardware design. The CC2541DK-SENSOR integrates all necessary components including the CC2541 SoC, six sensors, battery, and PCB antenna.

Which sensors are included on the CC2541DK-SENSOR and how are they interfaced?

The CC2541DK-SENSOR includes six surface-mount sensors: TMP006 (IR temperature), SHT21 (humidity), T5400 (barometric pressure), KXTJ9 (3-axis accelerometer), IMU-3000 (3-axis gyroscope), and MAG3110 (3-axis magnetometer). All connect to the CC2541 SoC via a shared I²C bus with individual enable signals - allowing selective activation to minimize power consumption. This architecture is implemented in the CC2541DK-SENSOR's factory firmware.

Does the CC2541DK-SENSOR require external programming hardware or debug tools?

No, the CC2541DK-SENSOR does not require external programming hardware for basic operation. It ships with pre-flashed firmware supporting BLE advertising, sensor readout, and GATT service exposure. Firmware updates or custom development require a CC Debugger and SWD interface - but these are not needed to run the TI SensorTag app or evaluate sensor behavior out-of-box with the CC2541DK-SENSOR.

Is the CC2541DK-SENSOR compatible with Android devices?

The CC2541DK-SENSOR hardware supports Bluetooth 4.0 LE and is technically compatible with Android devices, but official app support was limited at launch. The TI Bluetooth SensorTag app was only released for iOS (iPhone 4S+, iPad 3+, iPod Touch 5th gen). Android integration requires third-party BLE apps or custom development - unlike the native iOS experience delivered with the CC2541DK-SENSOR.

What regulatory certifications apply to the CC2541DK-SENSOR RF board?

The RF board inside the CC2541DK-SENSOR holds FCC ID ZAT2541SENSOR, Industry Canada ID 451H-2541SENSOR, and TELEC ID 007-AB0083. It is certified for operation in the 2.400–2.4835 GHz ISM band under FCC Part 15, IC RSS-247, and ARIB STD-T66. These certifications cover the integrated PCB antenna and apply to the assembled kit - not to modified or disassembled units.
