XinaBox 5-24v Power Supply Buck Converter

xChips are a rapid electronics development ecosystem to help reduce development time and simplify making custom products as well as aiding learning. Without soldering, wiring, breadboarding, or hardware knowledge you can assemble a circuit in minutes, and concentrate on coding.

xChips are compatible with the platform you want to use and bridges are available for the most popular pltatforms; Raspberry Pi, Minnowboard, Beaglebone, Micro:bit, Pixhawk and 96 boards. Rather than bridging to Ardunio, we offer compatible cores for Arduino Uno, the CC01, and for Arduino Zero, the CC03.

xChips utilise I2C, and due to this bus architecture, unlimited expansion of circuits is possible. Limitations of I2C addresses have been negated by development multiplexers.

Because of its simple connection method, it is easy to build quickly - for prototyping and small product runs

xChips connect to each other using an xBus connector, available from RS 174-4977.

Some xChips need an xPDI connector (RS 174-4974) to connect to programming interfaces, such as the IP02 or IP03.

This xChip is a power module that charges a 3.7v LiPo battery via power input from a Micro USB power source. Unless connected to this Micro USB power source, the circuit draws power from the LiPo battery and supply the xBus with power.

The on-board MCP73831 LiPo battery charging IC offers a simple and efficient battery charging solution with various features, such as Auto Off, Cell Preconditioning, Cell Temperature Monitoring, Reverse Polarity Protection, Status Indication and Under Voltage Protection/Brown-Out. It is capable of charging the battery at a rate up to a maximum of 500 mA.

The equipped PAM2305 is a step-down current-mode, DC-DC converter. At heavy load, the constant frequency PWM control performs with excellent stability and transient response. To ensure the longest battery life in portable applications, the PAM2305 provides a power-saving Pulse Skipping Modulation (PSM) mode to reduce quiescent current under light load operation to save power.
