The 4KEY touch development kit is a touch solution development board developed by CMS79FT738, which can support 4KEY touch buttons. This kit provides developers with an ideal evaluation environment and supports the development of user touch solution devices. The development board includes 4KEY touch module, 14PIN external IO port. Connect the simulation port of the kit to a PC through the simulation port, and you can edit and debug the program in the development environment (IDE) of the CMS. The CMS79FT738 main control chip used in this development board is a new type of touch MCU, which has the characteristics of high signal-to-noise ratio, high sensitivity, high reliability, etc. It adopts brand-new patented technology to effectively solve the conduction immunity (CS) problem and excellent conduction disturbance.
