Chapter 1 Overview
1.1 Introduction
HCTBLE42S1D is a small-sized SMD Bluetooth module developed based on nRF51822
produced by Nordic of Norway. It uses a 16Mhz industrial grade crystal to ensure its industrial
characteristics and stability.
nRF51822 comes with high-performance ARM CORTEX-M0 core and Bluetooth 4.2 radio
frequency transceiver and protocol stack, and has rich peripheral resources such as UART, I2C, SPI,
ADC, DMA, and PWM. This module redeveloped some IO ports. For details, please refer to the pin
definition, which is convenient for users to carry out multi-directional development. The module
has built-in on-board PCB antenna, it does not require external antennas.
