Hi
I started to compare the "EPD extension board" (EPD) with the embedded artists E-Paper Adapter Board (EA)
Here are some of my results (not sure if i am correct, please confirm or correct me)
EPD: 5V, with serial flash, 5V tolerant, analog Temperature value
EA: 3.3V, no serial flash, not 5V tolerant, I2C Temperature sensor
Here is a table of matching pins (at least what i think). Please note, that the polarity might be different for EPD and EA.
| EA Pin | EA Name | EPD Pin | EPD Name | Code |
|---|---|---|---|---|
| 1 | GND | 20 | GND | - |
| 2 | 3.3V | 1 | 5V | - |
| 3 | SCLK | 7 | SPI CLK | - |
| 4 | MOSI | 15 | SPI MOSI | - |
| 5 | MISO | 14 | SPI MISO | - |
| 6 | SSEL | 19 | /EPD_CS | Pin_EPD_CS |
| 7 | BUSY | 8 | BUSY | Pin_BUSY |
| 12 | Reset_Disp | 10 | /RESET | Pin_RESET |
| 11 | PWM | 9 | PWM | Pin_PWM |
| 14 | Discharge | 12 | Discharge | Pin_DISCHARGE |
| 13 | PWR CTRL | 11 | Panel On | Pin_PANEL_ON |
| - | - | 13 | Border Control | Pin_BORDER |
| 9 | I2C SCL | - | - | - |
| 10 | I2C SDA | - | - | - |
| - | - | 6 | Temperature | Pin_TEMPERATURE |
| - | - | 18 | /FLASH_CS | Pin_FLASH_CS |
Use this information on your own risk. Perhaps someone can confirm this table...
