A CPU-based dual-channel fast servo (general purpose PID controller). It can be controlled by Kasli or work stand-alone with PoE supply.
Design files (schematics, PCB layouts, BOMs) can be found at Stabilizer/releases.
Features:
- STM32H743ZIT6 Microcontroller (Cortex M7, 400MHz)
- Dual 16bit ADC (LTC2310-16) with x2, x5, x10 PGA (2MS/s)
- Two 16bit DACs (AD5542A) with 1us settling time
- Powered from POE, EEM or 12V supply
- EEM connector - can be configured for upstream or downstream operation
- 10/100Base-T Ethernet
- Connectors and mounts for optional AFE module
- IDC connectors for BNC-IDC breakout of microcontroller analog inputs and outputs (3× 16-bit 3.6 MSPS ADC & 2x 12-bit 1MHz DAC)
Under development by Quartiq. Dual channel PID and Ethernet already supported. Github
