简介
Brief Introduction
SKB378 是一个高度集成的蓝牙 5.2 模组，可用来在 2.4GHz ISM 频段内做高速率、短距离无线通信。
模组基于 EFR32BG22 蓝牙无线收发芯片，内部集成 32 位 ARM Cotex-M33 处理器，主频 76.8MHz，同
时内置 32kB RAM 和 512kB Flash，支持模拟或者数字外设。SKB378 提供了低功耗高性价比的蓝牙传输
和 AOA 定位应用。
The SKB378 is a highly integrated BLE 5.2 module, designed for high data rate, short-range wireless
communication in the 2.4GHz ISM band. The module is based on EFR32BG22 radio transceiver IC,
which integrates a 32 bit ARM Cortex-M33 76.8MHz CPU, 32kB Data RAM, 512kB Flash memory and
analog and digital peripherals. The SKB378 provides a low power and high cost-effective
BLE solution for wireless transmission and AOA positioning.
