# Build Guide

## Required Components
You will need the following tools and components to build the Basketweave (not included in the kit):
- Soldering iron and solder
- Phillips head screwdriver
- Flush side cutters
- No-clean flux (recommended to prevent bridging on USB pins)
- 68 MX style switches
- 5 PCB mount 2u stabilizers
- Keycaps (check compatibility, this layout uses many non-standard keys)
- USB Type C cable
## Included Components
The following components are included in the Basketweave keyboard kit:

| C3, C4  | 0.1uF Capacitor        | 2
| C5      | 4.7uF Capacitor        | 1 | The footprint on the PCB is meant for an electrolytic capacitor - ceramic will work but will be awkward to fit.
| D1-68, D72   | 1n4148 Diode      | 69
| D69, D70 | 3.6V Zener Diode      | 2  | Keep separate from the 1n4148 diodes

| POWER   | 3mm LED                | 1
| R1, R7  | 1.5k Resistor          | 2 | Make sure to get 1/8 Watt resistors since 1/4 (a common power rating) is too big for the footprint.
| R2, R5  | 5.1k Resistor          | 2 
| R3, R4  | 75 Resistor            | 2

| U1      | ATmega32A              | 1
|         | 40 pin IC socket       | 1
| RESET, BOOT | 6mm push button    | 1
| Y1      | 16MHz Crystal          | 1
|         | EC11 Rotary encoder    | 1
|         | Knob                   | 1
|         | M2 6mm standoff        | 11
|         | M2 10+3mm standoff     | 6
|         | M2 6mm screw           | 6
|         | M2 4mm screw           | 16
|         | Rubber Feet            | 4
|         | Basketweave PCB        | 1
|         | Bottom Plate           | 1
|         | Switch plate           | 1

### Step 1. Zener Diodes (D69, D70)
**This part has specific orientation** - black line on the diode lines up with the square pad (points right)

### Step 2. Resistors (R1-7)
Orientation does not matter. Solder based on the labeled values.
| Ref    | Value |
| ------ | ----- |
| R1, R7 | 1.5k  |
| R2, R5 | 5.1k  |
| R3, R4 | 75    |
| R6     | 10k   |

### Step 3. 1n1418 Diodes (D1-68, D72)
**This part has a specific orientation** - black line on the diode lines up with the square pad (points up)

### Step 4. Capacitors (C1-4)
Orientation does not matter. Solder based on the labeled values.
| Ref    | Value |
| ------ | ----- |
| C1, C2 | 22uF  |
| C3, C4 | 0.1uF |

### Step 5. USB Port
Solder one of the large legs first and check that the port is flush before soldering the other three legs. \
Solder the smaller pins by applying no-clean flux across the pins, then drag a small amount of solder across the pins until all the holes are filled.

### Step 6. Capacitor (C5)
**This part has a specific orientation** - longer leg goes in square pad (white mark on the capacitor points up)

### Step 7. Fuse
Orientation does not matter. Fold down after soldering.

### Step 8. Crystal (Y1)
Orientation does not matter.

### Step 9. LED
**This part has a specific orientation** - shorter leg and flat side of the LED line up with the square pad

### Step 10. Push Button (RESET, BOOT) and IC Socket
Push buttons have no specific orientation. \
Align the notch on the IC Socket with the markings on the PCB.

### Step 12. ATmega32A
Insert ATmega32A into the IC socket. Make sure the notch on the microcontroller aligns with the notch in the IC socket and the markings on the PCB.

### Step 13. M2 6mm Standoffs, M2 10+3mm Standoffs, M2 4mm screws
| Component          | Qty | Location     |
| ------------------ | --- | ------------ |
| M2 10+3mm standoff | 6   | Front top    |
| M2 4mm screws      | 5   | Front bottom |
| M2 6mm standoff    | 11  | Back         |

### Step 14. Switches and Rotary Encoder
Install the stabilizers, then place the plate on top. \
Install and solder switches and rotary encoder.

### Step 15. Bottom Plate
(optional) Flip the board over and insert foam. Screw angling feet into the bottom plate. \
Screw in bottom plate using 11x M2 4mm screws. \
Attach rubber feet.
