Getting Started

This guide explains how to get MSRC up and running quickly.

The goal is to have basic telemetry working with minimal configuration.

---

Requirements

You will need:

• An RP2040-based board (recommended: RP2040 Zero)
• A receiver compatible with MSRC
• At least one sensor (ESC, GPS, or analog)
• A USB cable
• A PC to configure MSRC

---

Download Firmware and Tools

Download the latest firmware and configuration tool: Releases

• Firmware: .uf2
• MSRC Link (configuration tool):
  • Linux: .AppImage
  • Windows: .exe
  • macOS: .dmg

---

Flash Firmware

1. Connect the RP2040 to your PC while holding the BOOT button
2. The board will appear as a USB drive
3. Copy the file MSRC-RP2040.uf2 to the device
4. The board will reboot automatically

---

Connect Hardware

Connect your receiver and sensors to the RP2040.

Typical connections:

• Power: 3.3V–5V (do not exceed 5V)
• GND
• Receiver telemetry signal (depends on protocol)
• Sensors (ESC, GPS, I2C, analog)

👉 See Hardware Setup for detailed wiring.

Configure MSRC

1. Connect the RP2040 to your PC via USB
2. Open MSRC Link
3. Configure:
   • Receiver protocol
   • Sensors to enable
   • Parameters (as needed)
4. Apply the configuration
5. Reboot the board

---

Verify Telemetry

Power the system and check telemetry on your transmitter.

• Discover sensors on your radio
• Verify values (voltage, GPS, ESC, etc.)
• The onboard LED should blink when telemetry is sent

If the LED does not blink, check wiring and configuration.

---

Optional: Lua Configuration (SmartPort only)

Configuration can also be done from the transmitter using Lua scripts.

After changing configuration, restart MSRC.

Troubleshooting

If something does not work:

• Check wiring and power supply
• Verify the selected receiver protocol
• Ensure sensors are enabled in configuration

👉 See Troubleshooting for more details.
