The XBee to USB Adapter is an usefull tool that allows to connect Personal Computers or a microcontroller in wireless networks using the famous XBee wireless modules.
This bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices, with a total of four signals.
This board is usefull to convert the RS-232 PC Serial Port signals to logic level datas used in any digital board that uses a serial port with 3.3V or 5V level lines.
The SSOP28-SOIC28 to DIP Adapter allows the mounting of 8-28 pin SSOP ICs and the mounting of 8-28 pin SOIC ICs; all the signals are broken out through two 0,1” DIP standard spacing headers.
This board carries the Allegro's ACS714ELCTR-05B-T hall effect-based ±5A linear current sensor, which offers a low-resistance (~1.2mΩ) current path and electrical isolation up to 2.1kV RMS.
This Relay Module 2-Channel is compatible with Arduino, it uses two optocouplers to grant galvanic insulation, and it can drive a load up to 7A 250VAC per channel.
The DS1307 serial real-time clock (RTC) is a lowpower, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of battery-backed NV SRAM. Address and data are transferred serially through an I2C, bidirectional bus.
