App Manager

Manage RP2350 apps on your TBD-16 directly from the browser. Install apps to the Pico SD card, choose a boot mode, and flash firmware — no card reader or terminal commands needed.

Browse the App Catalog for all available apps.

How it Works

Step 1 — Mount SD Card: Flash the USB Mass Storage firmware to the RP2350 so the Pico SD card appears as a removable drive.

Step 2 — Manage Apps: Open the mounted SD card, browse the app catalog, and install or remove apps. Apps are stored in the tbd-apps/ folder.

Step 3 — Choose Boot Mode: Eject the SD card, put the RP2350 back in BOOTSEL mode, and flash the firmware you want:

  • Bootloader — Boot menu that lets you switch between installed apps using the front-panel controls.

  • Groovebox Only — Flash the groovebox directly for single-app operation (no boot menu).

  • Flash Nuke — Erase the RP2350 flash completely. Use this to factory-reset or recover from a broken state.

Hardware setup:

  • Back USB-C Port #2 (closest to the edge) → RP2350 BOOTSEL + SD card

  • Back USB-C Port #1 → power (keep connected)

Browser: Chrome, Edge or Opera required (WebUSB + File System Access).

Time: 5–10 minutes

3 Choose Boot Mode & Flash
Safely eject the SD card drive from your computer first.
Then put the RP2350 in BOOTSEL mode again (hold BOOTSEL + press RESET).

🔀 Boot Menu (Bootloader)

Flash the custom bootloader. On startup, use the front-panel controls to choose which app to run from the SD card. Recommended when you have multiple apps installed.

🎹 Groovebox Only

Flash the groovebox directly — single-app mode with no boot menu. The device boots straight into the sequencer.

💥 Factory Reset (Flash Nuke)

Erase the RP2350 flash completely. Use this to recover from a broken state or remove the bootloader. After nuking, flash the groovebox or bootloader to restore operation.
