Meet the Terminus R808
**Release Announcement Link**=================
=Thanks To The Community=
=================
Woot! A big Thanks for the continued community support.
These little miner's continued advancements forward can't happen without it.

What the port face looks like. We've got USB-A for 5V power out, and a mini USB for control. 12V can be drawn from either a PCIe 6-pin jack or a 2.1/5.5mm barrel jack (for running off a brick). The blue knob is used to adjust core voltage from about 0.63 to 0.80V chip-level, basically the same range as the 2Pac. It can be assembled with a vertical (pictured) or right-angle (front-facing) adjuster.
This guy has an onboard microcontroller that handles fan speed via PWM, detects "ZOMBIE" condition and resets the chips automatically, and will overtemp-shutdown at 80C (to restart mining below 70C).
It's a 100mm square sitting on rubber feet, but there are M3 screwholes at each corner for stacking or mounting in a case.
This miner is built with 8x BM1384 hashing chips. I will be using this form-factor as a standard going forward, so newer versions with better chips will be physically compatible.
For all you flashy-light enthusiasts, it's got a base blue LED and blinks white with returned shares.

Todo: Place useful consolidated thread info here...
Q. How do I get one?
https://bitcointalk.org/index.php?topic=1845307.msg32983042#msg32983042Q. I heard there is extra startup parameters for the Terminus?
The default should be fine, but to adjust the startup behavior these extra options are available:
--gekko-start-freq <arg>
Ramp start frequency MHz 25-500 (default: 100)
--gekko-step-freq <arg>
Ramp frequency step MHz 1-100 (default: 25)
--gekko-step-delay <arg>
Ramp step interval in seconds, range 1-600 (default: 15)
Q. How fast do these things mine at?
With the default settings, this miner should produce 66Gh/s @150MHz.

I had 2 of them go zombie and didn't look like they were coming back.
