##### Stabilizer
The stabilizer module is a CPU-based dual-channel fast servo. It can be controlled by Kasli or work stand-alone with Power-over-Ethernet (PoE) supply.
- 400MHz STM32H743ZIT6
- dual 16bit ADC with x2, x5, x10 PGA (2MS/s)
- 16bit AD5542A DAC (1µs settling time)
- PoE supply
- 10/100Base-T Ethernet
- connectors for optional analog front-end (AFE) module
- IDC connectors for IDC-BNC extension for digital IO and aux analog inputs and outputs
It can be used as a general-purpose PID controller. Several AFE extensions are under development including high current power supply for magnets.

##### Thermostat
This module is a 2-channel temperature controller EEM based on the Maxim MAX1968 driver, capable of driving 6W into a TEC or resistive heater. The sensor interface is based on AD7172 ADC.
Preliminary specifications:
- Channel count: 2
- Sensor: 10k NTC thermistor
- Load (heater/TEC) drive: up to 8W (+-2A with 4V compliance)
- Form factor: 3U module or stand-alone AL enclosure (Hammond 1455C1202).
- Output connectors: Sensor and load connect via either terminal block connector on the front panel or via internal 100mil pin-header.
- Programming interface: Ethernet accessible via RJ45 connector on the front panel
- Power supply: +12V DC (1.5A max) supplied either by a front-panel barrel connector, via 100mils Zotino connector, or PoE (up to 30W).
- STM32 MCU
This module is still in development and is not currently available.

##### SU-Servo
With the SU-Servo feature of ARTIQ, the AD9910 variant of Urukul (which has fine amplitude control) can be used in combination with the Sampler ADC to form a laser intensity servo. In this application, the Urukul card drives AOMs and photodiodes are connected to Sampler to monitor laser intensities. When ordering your system, specify that you want SU-Servo integrated into the gateware.
See the <a href="/experiment-control/sinara-core/">Sinara Core</a> page for the relevant devices (Kasli, Sampler and Urukul).
