Fortunately, I was qualified to try out the CH549EVT from Qinheng Electronics. Thanks to Qinheng Electronics and EEWORLD for providing the learning and communication opportunities!
This time I applied for a set of CH54PEVT learning and development board. The onboard CH549L microcontroller is an E8051 core enhanced single-chip microcomputer launched by Qinheng Electronics, which supports a maximum system frequency of 48MHz and an average instruction speed 8 to 15 times faster than the standard MCS51. The CH549 chip has very rich resources, with built-in 12-bit ADC module, capacitive touch button detection module, TS temperature sensor, built-in clock, 3 groups of timers and 3-way signal capture, 8-way PWM, 4 groups of asynchronous serial ports, SPI and other functional modules, supporting full-speed and low-speed USB-Host host mode and USB-Device device mode as well as USB PD and type-C.
From the above introduction, it can be seen that the application space of CH549 is very wide, especially USB, USB PD, type-C and capacitive touch have further expanded its application space.
Below are some photos of this CH549EVT learning development board to share with you.
1. Overall. Along with the development board comes Qinheng's CH340 USB to serial port module; a relatively soft and good quality double-ended type-A data cable; and samples applied for at the same time;
2. Overall and partial details of the development board. The overall workmanship of the development board is relatively exquisite. All IO ports of CH549 have been brought out. The board is also equipped with RS232 interface, USB, type-C, Micro USB, TF socket and other interfaces. There are also four spring touch buttons and 4 LED indicators. In addition, 5V and 3.3V power supplies can be selected. These resources provide great convenience for development, debugging and learning.

3. USB to serial port module: This small module is very delicate and has very comprehensive functions.
From the above pictures, we can see that this is a very good learning development board. Qinheng Electronics is also very considerate and provides USB to serial port modules, data cables and samples for trial users to facilitate learning.
Thanks again to Qinheng Electronics!
