JL AC632N IoT Chip Development Board System Board with Downloader for Universal Bluetooth Application Development

Introduction:
- AC632_DevKit V2.0 is a system board designed for general Bluetooth application development. The AC6321A4 equipped belongs to the JL Bluetooth chip, which is a low-cost and ultra-low power Bluetooth data transmission system level SOC, designed for smart homes, IoT control and other wireless data transmission smart devices. The chip integrates a 32-bit CPU to support floating-point and mathematical function acceleration operations, and is equipped with a Bluetooth modem, baseband, and analog RF module. It supports Bluetooth V2.1/V4.2/V5.3 versions, ultra-low power Bluetooth broadcasting, connection standby, network transmission, etc. It has low latency long-distance data transmission capability, meeting the requirements of general music, communication, intelligent control, sensor collection data transmission and processing. At the same time, it comes with a PMU module that provides multiple low-power working modes, can use LDO or DCDC power supply modes, and can charge lithium batteries. At the same time, the chip provides complete FCC and BQB certification, reducing the cost of certification during secondary product development of the AC632 chip.

- The AC632-DevKit V2.0 development board mainly consists of a base board AC632-DevKitBoard V2.0 and a top board AC6321A_TOP V2.0, providing rich peripheral interfaces such as USB, key ADC, IIC, SPI, Q-decoder, MCPWM, LED Control, etc. Application solutions suitable for BluetoothSmart and SmartReady.
