Breakout board compatible with the XBee format and equipped with the Bluetooth 4.0 (Low Energy) module of the Texas Instruments CC2541.
It is particularly suitable for use with the "Bluetooth Shield" (not included - see related products) specially designed to accommodate three different types of Bluetooth modules (HC-05, BLECC2541, BLE40).
Breakout board dimensions with a Bluetooth module (mm): 33x25x10.

N.B. the "Bluetooth Shield" is not included, see related products.

Technical specifications of the Bluetooth module CC2541

Bluetooth 4.0 (Low Energy) module compliant with ISM 2.4 GHz, master/slave operation mode with transparent data transmission, based on the Texas Instruments CC2541 chip with 256K of Flash memory and 8K RAM.
It can be controlled through simple AT commands (via UART) or programmed with custom applications. Ideal for use in projects where a Bluetooth connection is needed, such as between microcontroller and PC.

Power supply between 2 V and 3.6 Vdc.
Dimension (mm): 27x13x1.6, weight: 5 grams. N.B. SMT assembly.
