1.54-inch multi-function ink screen

Inherits all the functions of 2.9 inches (clock/weather/reading/picture/network configuration/settings/SD/temperature and humidity/OTA)
and adds JGP decoding function, using real 4 grayscale + pixel jitter to make the picture show more details
. Due to frequent updates, the engineering attachments are no longer released. The firmware release address is
an epic update, reading supports custom ttf fonts and font size adjustment.

welding, assembly guide
welding
screen part: first weld 1uf/0402 capacitor, then weld FPC seat
serial download part: first weld LBC847BDW1T1G
button part: lower the temperature during welding to avoid scalding the internal pressing structure, the left and right feet are close to the pad and aligned with the inner edge of the silk screen, the bottom of the button is close to the PCB board, keep it vertical, see the picture below for details. Others are assembled
according to the principle of small first and then large. The power switch cap is extremely difficult to install and needs to be assisted by tweezers. Before installation, check whether the gap of the switch cap can be put into the handle of the power switch. If not, please use a knife to cut it. Put the switch cap into the shell first, and then put it into the PCB board. When putting it in, pay attention to whether the gap of the switch cap is aligned with the switch handle. Use tweezers to clamp the switch cap and pull it outward, and slowly put it into the PCB to prevent the button cap from falling out of the shell . The shell and back shell are recommended to be printed with Jiali Chuang nylon. YYDS has two shells, the difference is the square panel and the rectangular panel. The power switch button cap is too small and can only be printed by yourself with FDM. How to use the panel : open the editor, find the panel page in the left column to open it, and then find the order-panel order on it. Rectangular panel, you can customize the content at the bottom, you need to stick double-sided tape yourself (the panel thickness is 0.5mm, 0.8 may protrude a little bit) Square panel, just stuck on the screen, you need to polish the edges slightly until it can be stuck on the shell (the panel thickness is 0.5-0.8mm, 0.8 is the best) Multi-picture cat killing (what ancient network language) Default clock, clock with weather day countdown, custom sentence B powder display, mode selection interface weather interface file selection interface reading, picture interface picture viewer, switch up and down, press and hold 3 to call out the list, stay still for 60 seconds sleep assembly back rectangular panel-shell positive panel-ordinary-shell positive panel-sinking-shell positive panel-moon-shell
