+This variant attempts to be as faithful to the Blackmagic mini as
+possible, but also has several differences. This board has been built
+and functions.

+
+## 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](http://www.keil.com/support/man/docs/ulink2/ulink2_hw_connectors.htm).
+
+## Differences
+
+### Uses 0603 [1608 Metric] components
+
+The layout is intended for reflow soldering.
+
+### 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](https://www.sparkfun.com/tutorials/114).
+
+### 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 then bootloader mode. Then
+[scripts/bootprog.py](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 regular firmware updates.
