Hardware Platform Support

In the Introduction to Wireless Communication Modules chapter, the concept of "main chip" is introduced. In practical applications, modules of various models manufactured based on the same series of chips from the same manufacturer often have similar functions and characteristics and usually use the same development tools and drivers. For easier expression and classification, the concept of "platform" is generated to refer to these different module models based on similar main chips.

Chip Manufacturer and Product Introduction

Currently, the main chips of various types of cellular communication modules supported by QuecPython are usually from four manufacturers of Eigencomm, Unisoc, Qualcomm and ASR.


Unisoc (Shanghai) Technologies Co., Ltd. is a leading integrated circuit design company in China and one of the few companies in the world that master communication technologies for various scenarios, including 2G/3G/4G/5G, Wi-Fi, Bluetooth, FM radio, and satellite communication. In 2018, Spreadtrum Communications (Shanghai) Co., Ltd. and RDA Microelectronics Co., Ltd. were merged and rebranded to Unisoc, achieving a powerful combination and leading the development of China's chip industry. The rise of Unisoc breaks foreign chip monopolies and leads the 5G chips, becoming a benchmark in China's chip design industry.
