¶ Board silkscreen ↔ MPF number reference
Cross-references every physical board's silkscreen pin labels (what you can actually read off
the board in a photo or in person) against the MPF chain-board-index numbers this project's
config uses (0-0-8, 2-1-16, etc.). Built by extracting the embedded photos and per-pin data
tables from board Overviews.xlsx (never previously pulled out of that file into a real doc) —
see docs/board-photos/ for the saved images this doc references.
This reflects board Overviews.xlsx's original/historical pin assignments, not necessarily
what's wired today. Several components have moved since (flippers, slings, plunger, trough-eject
→ Cobra board — see CHANGES.md entries 11-14; the trough opto bridge landed on chain2-0x20
2-0-16…22, not chain2-0x21; the bottom lanes and rollover button are on 2-0-27…31), and
every part not wired to a controller yet has no pin number at all (hardware-draft.yaml). Many
of the sheet's names are retired too: s_vukmid/s_vuktop → s-vuk1..4, s-dropper →
s-vuk6, s-target-e/r/m/l… → s-target1..7, and s-orbit-top doesn't exist. The real 5th
switch on the bottom-lane harness (2-0-29) is now s-button, the big rollover button; the
sheet's own separate s_bottomlane5 and s-button rows predate that and don't match it. For current, live status, always check
tools/hw_console/data/components.yaml / docs/wiring-guide.md — this doc is for identifying
which physical pin a given MPF number lands on, not for what's currently wired there.
¶ How to use this with a photo
- Identify the board family from the photo: CobraPin (green PCB, "COBRAPIN PINBALL
CONTROLLER" silkscreen, STM32 chips) or red board / PSOC4200 (red PCB,CY8CKIT-049-42XX
silkscreen, PSoC 4 chip,P0.x/P1.x/P2.x/P3.xpin labels along the header edges). - For CobraPin: read the connector label (
J1-J12, silkscreened near each header) and the pin
position within it, then look up that connector/pin in the CobraPin connector
table below. - For a red board: read the
P#.#label next to the pin, then look up that physical pin in the
PSOC4200 table below for the specific board (chain 2,
address0x20-0x23) — the four red boards are physically identical and not distinguishable
from silkscreen alone; which one you're looking at comes from which position it occupies in
the chain2 daisy-chain (seedocs/opp-hardware-reference.md), not anything printed on the PCB. - Cross-check the resulting MPF number against
tools/hw_console/data/components.yamlfor what's
actually wired there today, not just what this historical sheet says.
¶ CobraPin (chain 0 / chain 1)
The coil bank's silkscreen prints the MPF number directly next to each pin (visible above:
0-0-8, 0-0-9, 0-0-10, 0-0-11, 0-0-0, 0-0-12, 0-0-13, 0-0-14 for Bank A, continuing
through Banks B/C) — for the solenoid banks, the photo itself is the reference, no lookup table
needed.
The header connectors (J1-J12, used for switch inputs and the inter-board ribbon chain)
silkscreen the MPF number directly too — confirmed on this cabinet's own board (the close-up
photo above reads 0-0-1, 0-0-2, 0-0-3, GND, 0-0-8-0-0-11 under a "SERVOS" bracket,
then 0-0-27-0-0-24, GND, 0-0-19-0-0-16 — exactly J1 pins 2-9 then J2 pins 1-9 from
the table below, run together on one physical header) and by CobraPin's own
documentation: "The switch inputs are labeled in silkscreen with the MPF compatible numbers"
(same for coil outputs) — see cobrapin-official-wiki in docs/references/. An earlier version
of this doc claimed the opposite for these connectors specifically; that was wrong. The table
below (matching the silkscreen 1:1) is still useful as a compact reference and for the STM32/pin
detail the silkscreen doesn't show:

¶ PSOC4200 (red boards, chain 2)
Unlike CobraPin, the red board's silkscreen only prints the raw physical PSoC4200 pin label
(P0.0-P0.7, P1.0-P1.7, P2.0-P2.7, P3.0-P3.7) — never the MPF number directly. The
tables below (extracted from board Overviews.xlsx's PSOC4200 - Game Function sheet) give the
physical-pin ↔ MPF-number mapping for each of the four boards. "Game-function name (historical)"
is this sheet's own original device naming — cross-check against components.yaml for the current
name/status, since names and assignments have both drifted since this sheet was last updated.
¶ PSOC4200 red-board per-pin reference
Each board gets a generated visual (silkscreen pin / MPF number / device name, color-coded by
function) followed by the same data as a table — the visual for a quick glance while looking at
the physical board, the table for searching/scanning.
¶ chain2-0x20
