Description

Engineered for reliable integration, the WeAct Studio ELRS Mini Receiver V1 leverages the Semtech SX1281 transceiver paired with a precision temperature-compensated crystal oscillator (TCXO) to maintain a stable 2.4GHz link, minimizing frequency drift. Its ESP32-C3FH4 core provides ample processing power for the ExpressLRS protocol stack while enabling convenient over-the-air firmware updates and configuration via a built-in Wi-Fi access point.

The module’s 3.3V logic-level outputs are compatible with a wide range of flight controllers and servos, and its wide input voltage tolerance simplifies power supply design. The multicolor status LED provides immediate visual feedback on connection state, binding mode, and error conditions, streamlining setup and field diagnostics.

Key Features

  • High-Stability RF Core: SX1281 transceiver with integrated 52MHz TCXO ensures consistent performance across temperature variations.
  • Dual-Antenna Ready: Supports both included T-style and FPC antennas for flexible installation and signal diversity.
  • Wireless Configuration Portal: Built-in Wi-Fi allows for firmware updates and parameter tuning without a physical USB connection.
  • Multi-Function Control Button: Single tactile button cycles through bind, bootloader, and web update modes for streamlined setup.
  • Compact, Lightweight Design: Minimal 26x17x2mm footprint and 3-gram weight ideal for weight-sensitive micro and mini drone builds.
  • VBAT Telemetry Support: Monitors main battery voltage, enabling low-battery warnings and telemetry logging in compatible systems.

Applications

  • Micro and mini FPV drone builds requiring a compact, lightweight ExpressLRS receiver.
  • DIY RC aircraft and ground vehicles needing reliable, long-range control with PWM servo outputs.
  • FPV racing drones where low-latency telemetry and stable 2.4GHz links are critical.
  • Custom robotics projects leveraging the ESP32-C3's Wi-Fi for wireless configuration and diagnostics.
  • Fixed-wing UAVs utilizing VBAT telemetry for battery monitoring and flight endurance tracking.

Frequently Asked Questions

What is the output logic level of the PWM signals from this receiver?

The PWM output signals from this WeAct Studio receiver are 3.3V logic level. This is compatible with most modern flight controllers and micro servos. Ensure your connected device accepts 3.3V logic inputs to avoid potential damage or communication issues.

How do I put the receiver into bind mode or update the firmware?

Use the multi-function button on the receiver. A single press during power-up enters binding mode. Holding the button for a specific duration (typically 3+ seconds) on startup can activate the Wi-Fi web update portal or bootloader mode for firmware flashing. Consult the ExpressLRS documentation for precise timing.

Does this receiver support battery voltage (VBAT) telemetry back to the transmitter?

Yes, this receiver includes a dedicated VBAT monitoring input. You must connect your main LiPo battery's voltage (within the receiver's wide input range) to the designated VBAT pin. This allows battery voltage telemetry to be sent back to your ExpressLRS-compatible radio transmitter for low-voltage alerts.

Can I configure this receiver without soldering a USB-to-serial adapter?

Yes. The integrated ESP32-C3's Wi-Fi capability allows for wireless configuration. Power the receiver, use the button to enable the web update mode, connect to its Wi-Fi access point from a computer or phone, and access a web interface to change settings or flash new firmware.
