## Description

This Elecrow 4-channel RF remote control module pairs a 433MHz wireless receiver board with a 5-button RF remote controller. Each of the four latching relays provides passive (dry contact) output, allowing you to switch mains-powered appliances or DC loads up to 10A without additional circuitry. The module can also be controlled directly by a microcontroller via its standard interface. The self-locking (latching) mode means each relay toggles on and off with successive button presses. LED indicators (D1–D4) show the status of each relay channel, plus a power LED (D5). The included remote provides a range of 15–30 metres. Key Features 4 Latching Relay Channels – Self-locking mode with passive (dry contact) output 433MHz RF Wireless – 15–30 metre remote control range High-Current Relays – Rated up to 10A at 250VAC or 10A at 30VDC Microcontroller Compatible – Standard interface for direct MCU control LED Status Indicators – D1–D4 for relay status, D5 for power 5-Button Remote Included – Individual channel control plus all-off Specifications Working Voltage – 5–5.5V DC Working Current – ~220mA Quiescent Current – ~6mA Max Load – 10A at 250VAC / 10A at 30VDC RF Frequency – 433MHz Remote Range – 15–30 metres Relay Mode – Self-locking (latching) Module Dimensions – 65 × 50 × 20mm Package Contents 1× 4-Channel RF Receiver Module 1× 5-Button RF Wireless Remote Controller Warning: This module can switch mains voltage loads. Ensure all high-voltage wiring is performed by a qualified electrician and complies with local electrical regulations.
