Product Description

CC2541 UART Transceiver ready firmware BLE PCB module

NDB-T2541C is a Bluetooth Low Energy (BLE) module based on TI CC2541F256, an 8051 core BLE System-on-Chip (SoC). This PCB module integrates one 32 MHz crystal, one 32.768 kHz crystal, an LC balun, an RF matching filter, and a meander line antenna. It is pre-programmed with the BLE 4.0 stack and an application communication protocol over its serial interface. It enables users to quickly connect their application MCUs to build reliable BLE connection from their products to smartphones.
