On the back side, there are places to attach three resistors on the `(SENSOR)` side and three on the `(LED)` side, as shown in the figure. Both through-hole and chip resistors can be used, so use the parts of your choice. However, even for through-hole types, it is more stable to mount them without passing them through the holes when attaching the dial.
As mentioned earlier, the resistors depend on the adjustment, but it is recommended to leave the `(SENSOR)` side unpopulated and install 330Ω resistors on the `(LED)` side as a standard.
As for the resistors, it depends on the adjustment as mentioned above. By default, we recommended using the internal pull-up, leaving the `(SENSOR)` side unpopulated and installing a 330Ω resistor on the `(LED)` side. However, since the internal resistance value varies greatly from device to device, we now recommend using the `no_pull` variant of the firmware, with 33KΩ on the `(SENSOR)` side and 330Ω on the `(LED)` side.
For the 1x5 pin header, using an L-shaped one will fit well in the case.

#### Assembly
Currently, we have released up to the schematics. We will release the Gerber data soon, so please look forward to it!
The Gerber data for the main board is in `board/gerber/main.zip`. Together with `main_bom.csv` and `main_positions.csv`, this data can be used to order board manufacturing and assembly from JLCPCB. If you order correctly, you will receive a semi-finished board like the one below.

If you attach them facing outwards on the front side like this, it will be easier to route the cables during wiring. It is a good idea to not insert the inner pins all the way, but to leave them slightly raised to create a height difference. Be especially careful with `SENSOR I-H`, which will pass over the USB connector.
The following work on the back side can minimize the board thickness and at the same time avoid short circuits with components and heat dissipation problems.

### Firmware Flashing
This dedicated board also follows the general method for Raspberry Pi Pico, but since two RP2040s are mounted on the board, you need to flash two firmwares to each.
First, flash the sub-chip using the USB Type-C terminal labeled `USB 2`. The jumper labeled `U1 PWR U2` normally shorts `U1` and `PWR`. This is a setting where the power on the board is taken from the `USB 1` terminal. Temporarily change this to short `PWR` and `U2`.
In this state, connect the `USB 2` terminal to the PC while holding down `BOOT 2`. Copy `sub.uf2` or `sub_no_pull.uf2` to the drive named `RPI-RP2` that appears on the PC. If the writing is successful, the drive will disappear.
Once disconnect from the PC, and then flash the main firmware. Return the jumper setting to shorting `U1` and `PWR`, and connect the `USB 1` terminal to the PC while holding down `BOOT 1`. Similarly, copy `main.uf2` or `main_no_pull.uf2`. When the drive disappears, the flashing is complete.
## Photo Sensor Adjustment
The photo sensor readings should not vary greatly as they are taken inside the case, but differences may arise due to the brightness of the 3D printing material or the quality of the paper on which the Gray code is printed. If the dial reading is unstable or the rotation does not stop, the sensor value change range may not be within the expected range. In that case, please adjust the sensor paying attention to the following points.
