Tangga resistor: tombol k menghubungkan BTN (GPIO34) ke GND lewat Rk; pull-up 10k (R5) ada di PCB utama.
| Tombol | Rk | Tegangan BTN |
|---|---|---|
| SW1 Atas | 1k | 0,30 V |
| SW2 Bawah | 3,9k | 0,93 V |
| SW3 Kembali | 8,2k | 1,49 V |
| SW4 OK | 18k | 2,12 V |
| SW5 Lanjut | 39k | 2,63 V |
| tidak ditekan | – | 3,3 V |
Hanya satu tombol terbaca dalam satu waktu (cukup untuk menu). C1 100 nF di BTN meredam derau.
J1 = header 1×6 (urutan sama dengan J6 PCB utama: +3V3, GND, SDA, SCL, BTN, AUX tidak dipakai). Jarak antar board ±16 mm (atas PCB utama z 16,6 → bawah board interface z 33). Socket J6 8,5 mm + header biasa (6 mm masuk) tidak sampai, jadi perlu header pin panjang atau spacer. Cara pasang board ini (dudukan) belum diputuskan.
Dibuat oleh hardware/tools/gen_pcb_interface.py (penempatan, silkscreen, pour) + hardware/tools/autoroute/sisa.py
(routing, GND lewat pour). Render: render-atas.png, render-bawah.png.

This arm is not industrial and it will not be fast, but that is not my goal. But it will hopefully be a very nice looking arm fully capable of 6dof motion, cheap enough to keep it accessable but capable enough to…
It measures 46 × 36 mm and has 2 copper layers, 1.69 mm thick.
17 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the Mervs111/Line-Follower-Racer repository on GitHub, at the commit this page was made from: the board is hardware/board-interface/board-interface.kicad_pcb and its schematic arsip/hardware/ltm-sensor/ltm-sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Mervs111 before reusing the design.
