README.md
This variant attempts to be as faithful to the Blackmagic mini as possible, but also has several diferences.
Details
-
The schematic and board have both been designed using Cadsoft EAGLE v6.4.0.
-
The board size is 40mm x 16mm.
-
The programming connector is an ARM 10-PIN Interface as described here.
Differences
Uses 0603 [1608 Metric] components
Makes reflow soldering much easier.
Includes Level Translator
This board incorporates the same level translator used in the full-sized Blackmagic, so it can be used to safely program 2.7V or 1.8V systems.
USART Connector
The STM32F103's USART1 peripheral is broken out into a 0.1" header. The hole centres are slightly offset to allow a press-fit.
BOOT0 Button
As well as the standard button for entering USB DFU mode, this variant also provides a button for pulling the BOOT0 pin high to activate the STM32 SystemMemory bootloader. Hold this button when plugging in the module to enter bootloader mode where scripts/bootprog.py can be used to program and reprogram the chip over the USART1 interface.
This is useful for programming a brand new or 'bricked' blackmagic with the DFU firmware (src/blackmagic_dfu.bin), the standard DFU mode should be used for regualar firmware updates.
