Every detail, engineered.

One coinslot drives your entire shop. Up to 10–20 tablets share a single ESP32 unit — fewer devices to wire, fewer devices to maintain, and a noticeably lower power bill every month.

1 coinslot, up to 20 tablets

One ESP32 coinslot unit services the whole shop. Less hardware to buy, less wiring to run, less to go wrong.

Mas tipid sa kuryente

Fewer powered coinslot units means a measurably lower electricity bill — especially relevant for shops running 15+ machines.

Device Owner kiosk lockdown

Real system-level lockdown on every device. No accessibility hacks. Reboots survive, users can't escape the kiosk.

Easy to maintain

Centralised hardware means one point of maintenance. Fix or replace the coinslot once — all tablets benefit immediately.

OTA updates

Push APK updates to every tablet from the dashboard. No USB cables, no store visits. All units on the latest build in minutes.

Hardware watchdog

ESP32 v20d firmware with non-blocking WiFi reconnect, exponential backoff, and watchdog timer. Stable through brownouts.

Centralized is the recommended setup for shops with 5 or more tablets. Higher upfront cost, but the savings in hardware and electricity pay for themselves.

Each tablet runs its own dedicated coinslot. The simplest possible setup — plug in, install, go. Perfect for operators starting small or running a few standalone machines.

1 coinslot per tablet

Each machine is fully self-contained. Simple wiring, simple setup — no network dependency between units.

Mas barato nga license

Lower per-unit license cost. Ideal for operators who want to start with one or two tablets and grow at their own pace.

Device Owner kiosk lockdown

Same real system-level lockdown as Centralized. Reboots survive, the kiosk stays locked no matter what.

Atomic pulse counting

ESP32 firmware uses microsecond-debounced ISR with atomic snapshots. Coins counted correctly, even on dirty power.

Floating admin panel

PIN-gated bubble with full controls per unit. Triple-tap the timer to open — the operator's command center, always on screen.

Hardware watchdog

Same ESP32 v20d firmware — non-blocking WiFi, watchdog timer, brownout-resilient. Rock-solid per unit.

Non-Centralized is ideal for 1–4 tablets or operators who prefer a fully independent per-unit setup. Easy to expand one tablet at a time.

Hardware Wiring PisoLock Connection Diagram Non-Centralized · 1 coinslot per device

PisoLock Wiring Diagram — 12V Adapter → Buck Converter → ESP32 → Coinslot

Red wire — 12V power (+)

Black wire — Ground (GND / −)

Blue wire — Coin signal → 10KΩ → GPIO4

USB Type-C — Buck converter → ESP32

12V → Buck → 5V → ESP32 VIN via USB-C

The 10KΩ resistor sits in series on the SIG line between the coinslot and GPIO4 — protects the ESP32 from voltage spikes. 12V powers both the coinslot and the ESP32 VIN pin. The ESP32 then communicates with your Android device over WiFi.

Install PisoLock, step by step.

01

Enable Developer Options on your device

Go to Settings → About phone (or About tablet) and tap Build number seven times until you see "You are now a developer." Then go to Settings → Developer Options and enable USB Debugging.

02

Make sure no Google account is signed in on the device

Device Owner mode requires a clean device. If any Google account is active, sign out first or do a factory reset. This is a one-time requirement before the first install.

03

Download the installer files

Download both files below and place them in the same folder on your Windows PC. The installer will auto-download ADB tools if not already present.

— 06 / About

A small lab, building for one market well.

JClabs is an independent product lab based in the Philippines. We build for piso-net operators because we understand the floor — the dust, the coin jams, the brownouts, the late-night reboots. Every release is tested on the same hardware our customers run. No marketing fluff. Just software that works tomorrow morning, when the first customer drops a five-peso coin.

— Our Partners

Beyond software. A full ecosystem.

JClabs isn't just PisoLock. It's a growing family of products and services — all built with the same principle: real quality, honest value. PisoLock is the software lab. JCT Perfume and Crystal Nails are the lifestyle brands under the same roof.
