This module let you control four 250VAC - 10A relays with a 5V signal (15-20mA). Just send a logic TTL Active LOW signal from a microcontroller (Arduino, Raspberry Pi, 8051, AVR, PIC, DSP, ARM, MSP430) to switch the relay on. Inputs are Opto-isolated and there's Indication LED’s for Relay output status.
This Lipo battery charger board allows to charge and power your project with a stable 5V voltage from a Lithium batterie, a solar panel and/or from USB. No programming is required. Plug it in and it works. The internal charger IC handles all the power flow between the various components.
Evola µWiFi is a microcontroller module with integrated Wifi based on esp8266 chip, designed with minimal dimensions. It has an onboard 3.3V power regulator, includes all necessary pull-up resistors to operate and breaks out all esp8266 GPIOs pins.
This is a 5.5mm Jack Barrel, 2.1mm center pole breakout board. It can be used on a breadboard and is compatible with our AC/DC Power Jack wall wart adapters. The three output pins Tip, Sleeve and Shunt are broken out with 2.54mm pitch. Mounting holes are also present if you need to fix this securely.
This FTDI USB to TTL converter module has all FT232RL pins exposed and can operate at 5V or 3.3V. It allows you to program a PCB board like an Arduino, Genuino, Imagine or PIC. It's a useful module if you need RTS, CTS, DTR, DSR or RI signals for your serial communication. The USB connector is A/B type.
This Real Time Clock (RTC) module is based on the BQ32000 IC from Texas Instrument. It is controlled using I2C with 3.3V power and logic levels and use the same commands as the popular DS1307. This module has a Super capacitor wired to the RTC for power backup, so that your configuration can be saved without powering the device. Works great with Arduino,...
This ADS1115 module is a precision analog-to-digital converter (ADC) with 16 bits of resolution. Data are transferred via I2C and four I2C slave addresses can be selected. The module operate from a single power supply ranging from 2.0V to 5.5V. Easy to use with Arduino and Raspberry Pi I2C bus.
