Since my translation plugin is broken; this post will be primarily english – as long there is no working version of the plugin.
Some of you might remember my little Tweet on Nov. 16. about the PCB layout being ready for production. The pic isn’t actually the file I sent out for production; mainly because I found this bug…
So *surprise* the finished PCBs arrived; all 10 (I acutally got 11) were $29.90 shipped (to germany – I think I love you, ITead…)… (click for bigger image)
Beauty, aren’t they?! – so I got down into my lab and…
Har! Beauty 🙂
So. What is this anyway? CNCc is a CNC peripheral controller using an Atmel AtMega644 clocked at 20MHz and connected to the PC via USB (FT232). Features:
- USB 2.0 to serial using FT232
- 3x 10A / 250V Relais
- 1x 8A / 250V solid state relais, optocoupled.
- 1x 30A / 30V P-HEXFET motor driver. (For coolant pump)
- 1x high speed interrupt input
- 8x general porpose IO, configurabe as: GPIO, analog in and PWM out
- 1x NETSYNC header with high speed interrupt for net frequency synchronisation (for spindle RPM drive)
- 1x AUX header for general expandation (RPM sensor etc.). Features an I²C port.
- 2x Status LEDs, 1x Power LED and 3x LEDs indicating relais switched on.
I will use this baby to controll compressor, vac pump, shopvac and coolant flow (maybe spindle-RPM later too) via the PC.
The design isn’t fully tested yet, but tests are underway. I have the design and manufacturing files (CC-BY 3.0) here for you.
And then I got this package from seeed I ordered some time ago…
What might be in there…?
Wohoo! It’s the BusPirate 4.0! – Beauty!!
That’s all for now; maybe I will post something on MSP430 dev soon…
