motors. It records chamber pressure and acceleration to an on-board flash
memory chip, the contents of which can be downloaded after flight over USB.
-EasyMotor firmware is under development within the [AltOS](../AltOS) suite.
-
-Prototypes of v1 were built and evaluated, prototypes of v2 are built,
-with development of firmware and evaluation underay. This design is not
-yet for sale, but we hope to have it on the market by the end of 2020.

## Features ##
### User View ###
* Designed for use with a battery from 9-12V
* 1.5 x 0.8 inch board
+## Example Installations ##
+
+These photos are from snap-ring case forward closures machined by Bdale for
+test flights of EasyMotor. The sensor bodies are 316 stainless with a 1/8 NPT
+male boss, so the approach chosen is to drill a 1/8 inch touch hole all the
+way through the closure, then drill and tap 1/8 NPT female threads part way
+through the closure thickness. The hole gets filled with grease and the
+sensor screwed in.

## Artifacts ##
+The firmware for this product is part of the [AltOS](../AltOS) suite.
+
This board was designed using lepton-eda and pcb-rnd.
The hardware design files are available from
[git.gag.com](http://git.gag.com) in the project
[hw/easymotor](http://git.gag.com/?p=hw/easymotor;a=summary).
+## Availability ##
+
+Prototypes of v2 were built and successfully flown. An initial production
+batch is now underway, and we hope these will be for sale around the end of
+calendar year 2020.
