Overview
JCS devices are the physical electronics hardware that do the actual work.
The devices are split into functional families, where each family may have one or more device variants. For example, the JCS brushless motor controllers family contains motor controllers of varying features, capability and performance.
JCS Hardware Ethos
Common Interfaces
Aside from motor power connectors, all JCS devices share common connectors and pinouts. An analog connector on one device will be the same as an analog connector on another device.
Voltage Domain Separation
No internal rail voltages are generated from the DC Bus Input on any JCS power devices. This separates the noisy motive power rails from the lower supply voltage, which powers internal circuitry.
JCS Standard Voltages
JCS hardware is built around a set of standardised connectors and voltages.
Connectors
| Connector type | Current rating |
|---|---|
| Molex PicoClasp | 2.0A / pin |
| Molex PicoBlade | 2.5A / pin |
| Solder pads | Device dependent |
| Amass XT30 | 30A / pin |
| Amass XT60 | 60A / pin |
Voltages
| Type | Nominal | Max | Min | Notes |
|---|---|---|---|---|
| Power | 72V | 80V | 20V | High power DC bus supply. No reverse polarity protection. |
| Power | 48V | 52V | 20V | Low power DC bus supply. No reverse polarity protection. |
| Supply | 12V | 13V | 11V | Device internal electronics supply. Must be well regulated. Devices include reverse polarity protection where it can be fit in. |
| Supply | 5V | 6V | 4V | Low voltage device supply. Supplied by JCS network connections. Typically not supplied by user. |
