PineCone BL602 EVB information and schematics

  • Approximate dimensions: 26mm x 43mm
  • Board layout:

  • PineCone BL602 EVB schematic ver 1.1
    • Note: Current schematic, cc1 and cc2 share one 5.1KOhm resistor. Next schematic design will separate out the cc1 and cc2 has it own 5.1KOhm resistors
  • The board uses a CH340 Serial/USB adapter. This chip is commonly used in Arduino-class development boards. It is a full speed (12Mbps) USB interface and has vendor ID 0x1a86 with product ID 0x7523.
  • The GPIO pins (11, 12, 14, 17) plus the nearby RESET, POWER, and GND pins are all located on one side of the board, on J1 to provide JTAG connection.

Datasheets for components and peripherals


Misc notes

Planned to be available in at least three form factors:

  • NUT-01S -> ESP-01S
  • NUT-12S -> ESP-12S
  • NUT-15 -> RTL8723/AMPAK


Loading code

To load code, you must move the jumper to the edge closest to the board, press reset, load the code, move the jumper back toward the center of the board, and press reset again.

There are currently a number of loaders in progress, each with differing degrees of completeness and success on various operating systems.

  • In the build tree, there is BLFlashCube for Windows and a flash_build for Linux, neither with source.
  • bl60x-flash is in Python and has been reported successful on MacOS catalina (10.15.6) by Punnerud and madushan1000.
  • BLOpenFlasher is a WIP, written in go, by Bouffalo Labs to provide source for a flash utility.
  • bl602tool is a Python utility in development.
  • Bouffalo's Python Flash Loader is a new (Dec 02) flash loader by the makers of the chip.
  • Bouffalo's image build smooshes code and adds headers for downloads.
