ASR-2DF is a form factor reference design for the Afero ASR-2D Secure WiFi/BLE radio architecture (based on the ESP32 WiFi/BLE chipset). The ASR-2DF uses the Espressif ESP32-WROOM-32D module + the Afero Hardware Security Module.
This reference design is meant for customers to use as a starting point for their own designs. It is designed to solve for two different customer situations:
- As a separate board that is connected via a cable (connectorized) to the product's MCU board utilizing the on-board 3V3 supply, or
- As a module that is soldered down onto a host-PC board. Further stuffing options can select between an on-board or off-board 3V3 supply.
There are two different stuffing options (BOMs) to cover these two cases.
Use of the pre-certified Espressif ESP32-WROOM-32D module gives the board FCC/IC, TELEC, and other certifications.

The ASR-2DF design was built using Altium. The entire Altium project, including scripts that generate the output files, is included.
- ASR-2DF.PrjPcb is the toplevel Altium project file.
- ASR-2DF.SchDoc is the Altium schematic file.
- ASR-2DF.PcbDoc is the Altium layout file.
- ASR-2DF.IntLib is an integrated Altium part library for the design.
- AssyDrawing.PCBDwf and FabDrawing.PCBDwf are drawing templates for the Assembly and Fabrication drawings.
- documentation.OutJob and gerbers.OutJob are the "scripts" for Altium that you can use to generate all of the needed output files (pdf files, gerbers, pick and place info, et cetera).
- ASR-2DF.pdf pdf of the schematics, isometric view of the board, fab and assembly drawings; autogenerated.
- gerbers is the directory where the Gerber output files and ODB++ files are located. These are the files that one would use when you release the board to fab and assembly; autogenerated.
- gerbers/Bill of Materials-ASR_2DF.csv is the Bill of Materials for the debug version of the board; autogenerated.
- gerbers/Bill of Materials-ASR_2DF(ASR-2DF - Connectorized Appliance FF).csv is the Bill of Materials for the connectorized version of the board; autogenerated.
- gerbers/Bill of Materials-ASR_2DF(ASR-2DF - Solder Down Module FF).csv is the Bill of Materials for the modularized version of the board; autogenerated.
