+## Simplifying Robotics with Raspberry Pi® RP2040
+
+Cytron Maker Pi RP2040 features the first microcontroller designed by Raspberry Pi - RP2040, embedded on a robot controller board. The board also comes with 2-channel DC motor driver, 4 servo motor ports and 7 Grove I/O connectors, ready for your next DIY robot / motion control projects. Now you can build a robot, while trying out the new RP2040 chip.
+
+The DC motor driver onboard is able to control two brushed DC motors or single bipolar/unipolar stepper motor from 3.6V to 6V, providing up to 1A current per channel continuously. The built-in Quick Test buttons and motor output LEDs allow functional test of the motor driver in a quick and convenient way without the need of writing any test code. Vmotor for both DC and servo motors depends on the input voltage supplied to the board.
+
+Maker Pi RP2040 features all the goodness of Cytron's Maker series products. It too has lots of LEDs useful for troubleshooting (& visual effects), is able to make quite some noise with the onboard piezo buzzer and comes with push buttons ready to detect your touch.
+
+There are three ways to supply power to the Maker Pi RP2040 - via USB (5V) socket, with a single cell LiPo/Li-Ion battery or through the VIN (3.6-6V) terminals. However only one power source is needed to power up both controller board and motors at a time. Power supply from all these power sources can all be controlled with the power on/off switch onboard.
+
+Cytron Maker Pi RP2040 is basically the Raspberry Pi Pico + Maker series' goodness + Robot controller & other useful features. Therefore this board is compatible with the existing Pico ecosystem. Software, firmware, libraries and resources that are developed for Pico should work seamlessly with Cytron Maker Pi RP2040 too.
+CircuitPython is preloaded on the Maker Pi RP2040 and it runs a simple demo program right out-of-the-box. Connect it to your computer via USB micro cable and turn it on, you will be greeted by a melody tune and LEDs running light. Press GP20 and GP21 push buttons to toggle the LEDs on/off, while controlling any DC and servo motors connected to it to move and stop. With this demo code, you get to test the board the moment you receive it!
+
+While connected to your computer, a new CIRCUITPY drive appears. Explore and edit the demo code (code.py & lib folder) with any code editor you like, save any changes to the drive and you shall see it in action in no time. That's CircuitPython - very easy to get started. Wish to use other programming lauguages? Sure, you are free to use MicroPython and C/C++ for Pico/RP2040. For those of you who loves the Arduino ecosystem, please take a look at this official news by Arduino and also the unofficial Pico Arduino Core by Earle F. Philhower.
