A while back we started this post, showing off our Open Source VST104 development board:
Since then, we continued to develop on top of it.
Right now, we have our PUS-C standard implemented in Rust, running on top of FreeRTOS, all running on the VST104 board.
We are still developing and will keep extending it, but we can print and share some boards with other users.
Since we couldn’t keep soldering the boards ourselves, we decided to get some quotations from some providers.
To reduce the costs, we planned a board exclusively for development. I.e., all the components are by default not the military rated version.
But even taking into account that, the boards will likely cost around 500 Euros each.
This is a rough preliminary value, our quotation was lower than that. But there will be risks associated, and I rather give here what I believe is a realistic value.
So, my question to all of you is: Is 500 Euro per Unit a reasonable price to pay for an Open Source OBC development board? Will you buy one if we make a small Kickstarter-like event?
Depending on your feedback, we will decide the next steps.
You can find more in here:
- 2x CAN bus
- 2x I2C
- 2x SPI
- 4x UART
- System check & signals:
- WatchDogs/Kill Switches /CPU mode / Synchronisation./ Fault collector
- STM32L496 32.768 kHz (LSE), 26 MHz (HSE), 78 MHz (external oscillators)
- SWI and UART for programming and debug
- multiple temperature sensors, power management, independent peripherals isolators, payload sector
- Triple redundant flash memory
- (TBC) Triple redundant F-RAM (possibly empty, or single chip, depending on availability and cost)
Feel free to share your thoughts.
