1 Channel Power Relay Module 250V/10A 5V Control for Arduino

10/08/2026

250V/10A 1 Channel SPDT Power Relay Module 5V Control A relay is a digital switch to control much higher voltages and currents than your Arduino or other microcontroller board can. Controlled by a 5V logic voltage input, the relay will switch to allow current to flow or turn off, depending on your wiring. This 1-channel 5V control Single-Pole Double-Throw (SPDT) AC power relay board can be controlled directly via a microcontroller and switch up to 10 amperes at 250 VAC. The default state of the relay when the power is off for COMM (power) to be connected to NC (Normally Closed). This is the equivalent of setting the relay board IN pin to HIGH (has +5v sent to it). When you have power connected to the relay’s NO (Normally Open) connector and you set the corresponding IN pin to LOW (0V, or Ground), power will flow in from the COMM connector and out of the NO connector powering your device. Specifications: Polarity: Active Low – you must ground the control input to switch this device ON Relay Max Switching Voltage: 250 Volts AC Relay Max Switching: Current: 10 Amps AC Relay Control Voltage: 5.0V directly via microcontroller (Arduino, AVR, PIC, ARM, BoardX, Raspberry Pi, MSP430, etc) Relay Control Current: 20-30 mA Indicators: Red LED illuminates when +5V VCC control power is applied to the board. Green LED illuminates when control pin is pulled low (relay is activated). Size: 42mm x 17mm x 17mm (1.65 x 0.67 x 0.67 inches) L x W x H Package Includes: 1X 1-channel 5V SPDT 10A/250VAC power relay board Specifications and usage documentation Get it faster!

12V To 5V 3A 15W DC-DC Step Down Converter DC Power Supply Module Waterproof US

10/08/2026

12V Input to 5V Output 3A 15W DC-DC Step-Down Power Converter DC Power Supply Module Waterproof This 15W DC-DC converter converts a 12V input voltage (will operate with any input voltage from 8V to 24V) to 5V DC output at up to 3A. The module is epoxy sealed in a waterproof plastic housing with mounting tabs that can be used to mount the converter to a mounting plate, panel or bulkhead. Specifications: Epoxy sealed waterproof housingLightweight, compact, convenient to use and transportNon-isolatedWith overload / over-current / over / low voltage protection, stable performanceAuto recoveryInput voltage: DC 12V nominal, will operate on any input voltage from 8V to 24V DCQuiescent input current (no load attached): 96%Size (L x W x H): 38 * 27 * 23 mm (Length including mounting tabs is 52mm)Weight: 30gCase color: White Cable length: 12cm (approx)Operating Notes:As with any DC-DC converter, the input DC power supply powering this converter must be capable of providing the maximum power drawn by your load. If the input supply is not capable of providing the power, the converter will fold back the output voltage as necessary. Example: If your load draws 3A at 5V (15W), and the input supply is only capable of providing 12V at 1A (12W), the maximum output voltage the converter will deliver is 4V (12W/3A). The inputs and outputs are labeled on the sticker on top of the converter, the red and black wires are the + and – 12V input, and the red and yellow wires are the + and – 5V output.

2pcs TP4056 5V 1A Micro USB 18650 Lithium Battery Charging and Protection Board

10/08/2026

Dual Function: 1) Charge lithium cells from a 5V power source 2) Protect battery from over-discharge and over-currentCharge input: 5V DC • Maximum charge current: 1000mA • Charge cut-off: 4.2VDischarge protection cut-off: 2.5V • Over-current protection cut-off: 3AMicro-USB input • Size: 2.6×1.7cmThis is an enhanced USB-powered module for charging rechargeable lithium batteries using the constant-current/constant-voltage (CC/CV) charging method.This module provides constant-current/constant-voltage (CC/CV) charging, along with protection against over-voltage, over-discharge, over-current and short circuits to protect the battery and the device that it is powering.The device to be powered by the battery is connected to the module’s OUT+ and OUT- connectors and the battery is connected to the B+ and B- connections. When connected to USB power, the module provides up to 1A charge current until the battery is charged, then switches to a constant voltage mode to keep it charged.During use, if the battery voltage drops below about 2.4V, the DW01A protection IC disconnects the battery from the OUT connectors, disabling discharge to protect the battery from running at too low and self-destructing.When the module is then connected to USB power, it will trickle charge the battery to 2.9V (the over-discharge release voltage), at which point the charge current will be linearly increased to 1A maximum and the module will reconnect the battery to the OUT connections, allowing discharge of power from the battery to a connected load. Although the module cuts output power from the battery during an over-discharge situation, it still allows trickle charging of the battery to occur.The module also protects against overcurrent and short-circuit protection – it will cut the output from the battery if the discharge rate exceeds 3A or if a short-circuit condition occurs.This module is perfect for charging single cell 3.7V 1 Ah or higher LiPo cells such as 16550s and 18650s that don’t have their own protection circuit. It can charge two cells in parallel, however since the two cells share the charging current, they take twice as long to charge as a single cell.
