An ESPr Developer semi finished kit with Ultra low power consumption color LCD (Japanese page) from JDI (Japan Display Inc).
The components needed to operate the LCD are fully mounted, making it easier to get started for those who are not eager to solder.
The pin headers on the shield can be inserted to the breadboard too, allowing it to also work as a pitch converter board for the LCD.
Please be advised that this product is a semi finished item, therefore the LCD must be fixed manually onto the board. The spacer for fixation is included in the kit, however please prepare double sided tape (commercially available) separately.

[SJ1] decides action mode of LCD. The connector "EXTMODE" signal and GND are connected through [SJ1] at default. Also, the LCD should work just by running the software, enabling you to use it without any manipulation.
How to assemble
Lift up the black part on the connector, and insert the FPC of LCD. The junction (golden pattern) of FPC pin should face downwards.
Lower down the black part on connector and fix the FPC.
Over turn the board and stick the spacer with double sided tape.
Stick double sided tape on top of spacer too.
Fold the LCD down onto the spacer and you are finished assembling!
Please remove the IR protective liner on the surface when assembling.
About the LED for illumination
LEDs are optionally addable on to the shield. They can be connected directly to the connecting pad with current limit resistor. Please prepare white LEDs separately and solder them depending on your usage.
The LED pad is connected to versatile port, therefore by internalizing the software with the push button on the board, you will be able to control ON/ OFF of the LEDs.
