MicroPython Pyboard Lite v1.0

The Pyboard Lite is a nifty and potent electronics development board that runs MicroPython. It connects to your PC via USB, offering a USB flash drive to store your Python scripts and a serial Python prompt (a REPL) for quick programming. You'll need a micro USB cable (not included, but we have many options). It's compatible with Windows, Mac, and Linux. MicroPython is a full rewrite of Python (version 3.4) to run on a microcontroller. It has lots of optimizations for efficient running and low RAM usage. It runs bare - metal on the pyboard, giving you a Python operating system. The built - in pyb module has functions and classes to control board peripherals like UART, I2C, SPI, ADC, and DAC. Check out this video for an overview. There are three main ways to control the pyboard: 1. REPL: Connect via USB, and the board acts as a USB virtual comms port. You can use any serial program to get a Python REPL prompt, type, and execute commands right away, just like on your PC. You can also redirect the REPL to the pyboard's UARTs. 2. Remote script: Switch from REPL to raw REPL mode by sending ctrl - A. Then, send a Python script to the board to execute it immediately. There's a Python script to make this easy: run `python pyboard.py script_to_run.py` and it'll execute the script on the pyboard and return output. 3. From file: The pyboard has a built - in filesystem in the microcontroller's flash memory and an SD card slot for extra storage. When connected to your PC, it's a USB flash storage device. Copy a Python script named `main.py` to the filesystem, and the board will run it on startup, so you can run scripts without a PC. The hardware features an STM32F411RE microcontroller, a 96 MHz Cortex M4 CPU with hardware floating point, 512KiB flash ROM and 128KiB RAM, a Micro USB connector, a Micro SD card slot, GPIO pins, a 12 - bit analog to digital converter, 4 LEDs, 1 reset and 1 user switch, an on - board 3.3V LDO voltage regulator, and a DFU bootloader for easy firmware upgrades. The two mounting tabs on the pyboard can be snapped off cleanly if needed.

Using the Pyboard Lite is straightforward. First, connect it to your PC using a micro USB cable (which you'll need to provide). Once connected, you can start programming in three ways. You can use the REPL method to type and execute Python commands right away, similar to how you'd use Python on your PC. Just connect via USB and use a serial program to access the REPL prompt. You can also redirect it to the board's UARTs if you want. For the remote script method, switch to raw REPL mode by sending ctrl - A, then send your Python script to the board. There's a helper Python script to make this a breeze. The third way is to copy a Python script named `main.py` to the board's filesystem. When the board starts, it'll run this script, so you don't need to be connected to a PC. As for maintenance, keep the board in a dry and clean environment. When using the SD card slot, make sure to insert and remove the SD card properly to avoid data loss or damage to the slot. The board has a DFU bootloader in ROM, which makes it easy to upgrade the firmware. Just follow the instructions provided for the upgrade process. Also, note that the micro USB cable is not included, but you can choose from our wide selection. And if you don't need the two mounting tabs on the pyboard, you can easily snap them off.
