The Alpha board is our first full prototype for an open-source hardware
security module (HSM). It is a custom board with an STM32 Cortex-M4
microcontroller and an Artix-7 FPGA, flash-based keystore, separate memory
for the Key Encryption Key, etc. See the wiki for design documents.

rev01 was the "dev-bridge" board, a daughterboard for the Novena,
which talked to the Novena's FPGA through the high-speed expansion
connector.

rev02 is the Alpha board, our first full prototype for an open-source
hardware security module (HSM). It is a custom board with an STM32
Cortex-M4 microcontroller and an Artix-7 FPGA, flash-based keystore,
separate memory for the Key Encryption Key, etc.
The board's form factor (4 x 4 in, 101.6 x 101.6 mm) was based on the
Intel NUC mini-PC, but there were some issues sourcing enough cases, so
only a few of these boards were made.
rev03 is functionally the same as rev02, but in a Eurocard form
factor (100 x 120 mm, aka "3Ux120").
