v1 Hardware
This page reflects the earlier v1 prototype based on a different microcontroller. The wiki page for the current version is here.
Thermostat is 2-channel temperature controller EEM based on MAXIM MAX1968 driver , capable of driving 6W into a TEC or resistive heater. Sensor interface is based on AD7172 ADC
- 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 (can be broken out to a separate front panel with 2xD9, such as Schroff 30849-750).
- 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).
- TM4C ARM Cortex M4F CPU
- Idea is to make this board as advanced version of Thermostat_Thorlabs
- 1 LED per channel to indicate if the temperature is in range . Also have a single power LED.
- unique ID chip for TM4C and identification purposes.
Enclosure is Hammond PN 1455C1202
