5 W CCCV AC-DC Adapter GreenPoint® Reference Design

Direct AC LED driver with Bluetooth wireless dimming control

TWS earphone charging box

The TWS headset charging bin solution developed based on ML51 mainly has two major functions: data communication with the headset and charge and discharge management. Data communication is carried out with the headset through the pogo pin to realize pop-up windows and other functions that require data communication; the battery charging management unit has built-in lithium battery overcharge, over-discharge, short circuit, over-current and other protection functions, making the system stable and reliable.

remote text graphic display

This design uses GD32F350 as the main control, OLED12864 as the display screen, and the ESP8266 module as the display of the network connection module. After the system starts, it will automatically connect to the server (using server software written in Yi Language). You can then use the B2 button to obtain network time updates to the microcontroller system and calibrate the current time. In the receiving mode, pictures and text information from the server can be received. The microcontroller processes the transmitted information and displays it on the OLED screen. The design can be used as a task server, sending tasks from the network and then displaying them using OLED for easy viewing. It can be used as an electronic note and placed at home or at work to remind yourself of the work that should be completed today. The design also includes an alarm clock. Users can set an alarm clock to remind themselves, which can be used to wake up, task reminder, etc.

icebreaker++: icebreaker FPGA board, upgraded ECP5

icebreaker++ is a very nice and convenient little board. But it has a small flaw, the ice40 FPGA it uses is very simple, and it's generally fun to see people doing exciting projects with 5k LUTs. Sometimes it's convenient to have some extra space available when experimenting.
