Main Components:

  • DRA818V
  • STM32F103C8T6 microcontroller (one MCU only)
  • 5x Temperature Sensors
  • 4x RADFETs and Circuitry
  • 4x PIN Diode Experiments

Other Info

  • Ordered on 2023-08-23.
  • Designed to run a forked-and-modified version of vp-digi

Errata: Rev5 Main PCB

  • Forgot teardrops on main board.
  • Forgot I2C pull-up resistors (2k2 or similar)

Errata: Rev1 Test Fixture/Upgrades

  1. 5V trace has to be cut and re-run from J_5V_1 screw terminal (cut twice)
  2. ST-LINK header is mirrored. Used jumper wires to connect it.
  3. The alligator clip terminals should be on the edge of the board, and should maybe be a simpler footprint.
  4. The DIO enable switches should have resistors on them to prevent a make-before-break failure in the switch shorting 3V3/5V to GND.
  5. The UART and ST-LINK ports should have disableable 3V3 and 5V connections, because those lines get double-driven from the ST-LINK.
  6. Upgrade: Add optional LEDs lights to the DIO switch lines.
  7. Upgrade: Add a few easy-to-connect LEDs that can be run from the 3V3 and 5V breakouts for on-the-fly debugging/monitoring.
