octobot - board

[multigcs]

Since I use more and more the Servo42/57 drivers and play around with robots and many axes,
I thought I'd make a new board so that I don't have so much cable clutter
and everything is relatively compact.

ok, 8 axles is not really necessary, but my Parol6 has 6 axles + a servo gripper,
if I put a stepper gripper on it, I'm already at 7, so the 8th doesn't bother me any more :)

• 8 x opto inputs (5/24V can be installed in 2 groups)
• 8 x outputs (5/24V can be installed in 2 groups) / can also be used as PWM/RC servo output
• 8 x stepper axes
• 3 x encoder inputs with index pulse (3.3Volt level)
• 2 x I2C ports (3.3Volt level)
• 1 x modbus-rtu
• 1 x WLED output + one ws2812b onboard
• 1 x PMOD socket
• Current and voltage monitoring via ADC's
• Size: 100x100mm
• FPGA: eu.robotshop.com/de/pr...h-icewerx-ice40-hx8k-fpga (plugged on)
• Ethernet: wt32-eth01 (plugged on)

I'm not quite finished yet, maybe you or I can think of something else that might be missing.

I chose the FPGA because it is fast and relatively cheap to get in Germany.
The Ethernet board is also cheap and extremely stable.

The board can also be used for milling machines and lathes,
Initially, I wanted to put a standard NEMA17 driver socket on it,
but that would have been too big.
Maybe I'll make an add-on board with space for the drivers.
