Pyboard Lite v1.0
The "standard" build is listed first and is the default firmware that the pyboards are shipped with. Use this firmware if you are uncertain. The "double FP" builds use double-precision floating point instead of the standard single precision. The "threading" builds contain the _thread module and allow multithreading. The "network" builds have network drivers for WIZ820io included. All these different firmware are completely interchangeable and you can freely change from one to the other without losing the filesystem on your pyboard.
Installation instructions
Pyboard v1.x via DFU
One you have downloaded the appropriate DFU file it can be flashed directly to your pyboard
using a DFU programmer. You can enter the DFU bootloader on the pyboard by executing machine.bootloader() at the MicroPython REPL.
Alternatively, connect 3V3 with BOOT0 and reset the board. For information about DFU programming on Windows see this PDF. For Linux and Mac see here.
