Hardware Notes

Board Layout

Power Plug

The Minnowboard Max uses a 5.5 x 2.1mm barrel 5V power plug, and if bundled will ship with a 2.5A power supply. It is a Center Positive power supply, indicating that the center (tip) of the output plug is positive (+), the outer barrel is negative (-).

Center Positive 5V connector

Serial Console

The serial console port uses a 3.3v FTDI serial cable with a 6-pin connector. This is a reasonably common cable, also used on the Arduino Pro, Arduino Pro Mini and Arduino Lilypad.

Pin 1: Ground (GND) (Furthest from SATA connector)
Pin 2: CTS
Pin 3: VCC (3.3V)
Pin 4: TXD
Pin 5: RXD
Pin 6: RTS

NOTE: The serial pinout is flipped between A0 and A1. A0 boards are rare, and are only being documented for completeness.

Places that carry the appropriate Cable:

A0:

A1:

HDMI

The MinnowMax uses a Type D micro-HDMI connector. This is a standard port, for which cables and adapters can be readily picked up from most electronics stores

Low Speed Expansion (Top)

*** THIS IS PRE-PRODUCTION INFORMATION AND MAY BE SUBJECT TO CHANGE BEFORE PRODUCTION SHIPPING ***

The low speed connector uses 0.1" (2.54 mm) Male header pins in a 2 x 13 array, for a total of 26 pins. Pin 1 is the in the row closest to the power connector, and closest to the board edge.

NOTE: Pins 5-26 are shown above with their PRIMARY configuration, any pin may be switched to being a generic GPIO as well. This would give a total of 22 GPIOs, with two of those being PWM capable.

High Speed Expansion (Bottom)

*** THIS IS PRE-PRODUCTION INFORMATION AND MAY BE SUBJECT TO CHANGE BEFORE PRODUCTION SHIPPING ***

The High speed connector uses a TE Connectivity compatible 60-pin header. The generally recommended header is the 3-5177986-2, or the 60POS .8MM FH 8H GOLD part that rises 7.85mm, allowing for 3/8" standoffs at the corners to be used to attach the lure to the minnowboard.

SPI Header to Firmware flashing J1

*** THIS IS PRE-PRODUCTION INFORMATION AND MAY BE SUBJECT TO CHANGE BEFORE PRODUCTION SHIPPING ***

This is a pinned out port to allow for external flashing of the boot spi. Dediprog and Flyswatter devices have been tested and verified to work with this.

Power Connection J2 (SIP2_FAN)

*** THIS IS PRE-PRODUCTION INFORMATION AND MAY BE SUBJECT TO CHANGE BEFORE PRODUCTION SHIPPING ***

This is a 5V 2-pin pin out originally intended to be used for a CPU fan. The single core (E3815) and the dual core (E3825) however use passive heat sinks, and thus do not, under normal circumstances, need a fan. It is theoretically possible to pull upwards of 1A through this port, however you should refer to the released schematics to verify that number before attempting to use this for anything.

NOTE: This is not populated on the Single, or Dual core boards. This can be populated if needed, and will provide the above power

Switch Jumper J5

*** THIS IS PRE-PRODUCTION INFORMATION AND MAY BE SUBJECT TO CHANGE BEFORE PRODUCTION SHIPPING ***

This pin is intended to allow for power toggling via a remote switch or relay. It is fundamentally no different than pressing SW1, and behaves identically.

NOTE: This is not populated, by default.

SATA LED J6

*** THIS IS PRE-PRODUCTION INFORMATION AND MAY BE SUBJECT TO CHANGE BEFORE PRODUCTION SHIPPING ***

This is intended to be an HD LED type activity indicator, shorting the pins enables, leaving it out disables.

NOTE: This is not populated, by default.

Known Issues

MinnowBoard-MAX Open Bugs (Bugzilla)

Bugzilla:
We currently use the YoctoProject Bugzilla instance at http://bugzilla.yoctoproject.org
Bug Triage link can be found at: https://wiki.yoctoproject.org/wiki/Minnow_Bug_Triage

A1

Hardware

USB

There is a potential issue when using a powered USB Hub. If the hub, erroneously, provides power over the USB 3 or USB 2 input connector, the MinnowBoard MAX will use that as power. This is in violation of the USB spec, and will be rectified in a later revision of the MinnowBoard MAX.

Hubs known to cause this:

iXCC 7 Port USB 3.0 Hub
- Amazon Link
- iXCC Website

It is suggested that you check powered USB hubs to confirm that they do not provide power back to the board, as described, and if a hub is found to do this, please report it here. A hub found to be doing this should be used without being externally powered if used at all.

Firmware

See the bug list, linked above.

Unknown

Monitors

There is an issue with regards to some monitors not being able to display from the MinnowBoard MAX. Most monitors seem to be fine, but some will either completely not show a display (even at firmware boot-up) or may only show a display after the operating system is booting.

This is being investigated.
