T-Relay ESP32 4-Channel 5V Relay Module Board WiFi Bluetooth Smart Home Automation Remote Control Switch for Arduino DIY

Description: Name: T-type relay four-way relay MCU: ESP32-Wrover-B Flash: 4MB PS RAM: 8MB Communication protocol: UART, SPl, l2C, CAN, l2S, SDIO Wireless Protocol: Wi-Fi: 802.11 b/g/n Bluetooth: V4.2 BR/EDR and BLE On-board functions: four groups of relays, optocoupler isolation, 16 expansion IOs

HRS4H-S-DC5V relay: standard power consumption: 360～450 mw 1. K1 relay: I021 2. K2 relay: I019 four blue LEDs 3. K3 relay: I018 4. K4 relay: I005 relay working indicator

Maximum response/release time: 8ms/5ms Maximum operating current: 15A External power supply voltage input range: DC 12~24V Working temperature: -40~80℃ Support T-U2T downloader: It can be connected to use the T-U2T USB-to-serial downloader, which is convenient, fast, safe and beautiful. Can also be powered directly via Type-C USB

Since the motherboard does not burn the download chip, this product needs to use the T-U2T automatic downloader to upload the program. If you don't have a T-U2T, you need to purchase the companion version uploader. If you already own T-U2T, you only need to own T-U2T automatic downloader to be compatible with T-U2T series products, no need to purchase repeatedly.

Features: 1: Widely used 2: stable performance 3: Maximum operating current: 15A 4: The operation is simple and easy to understand

Package includes: T-type relay, four-way relay*1 pin header*2

Voltage: 2–24 V
