• M5Stack Main board : Switch Science
• HT16K33-SOP28 LED Controller Driver : Aitendo
• [OSL40562-IB] : 0.56 Inch Four Digit Display. Common Anode type.
• I2C level conversion board signal level 3.3V to 5V: Switch Scicence

Handmade Board

• use 4 Handmade Boards. A board has 2 LED Controller Driver and controls 8 Four Digit Displays.
• gerber : Data for manufacturing PCB. Format for Elecrow and so on.
• The drivers are distinguished by jumper pad (R6, R7, R8, R12, R13, R14).
• 
• 3.3V signal level for M5Stack has to be converted to 5V for LED Controller Driver.
