ODSv1.0.0-PP-T41v0.1.1

Changes:

• SPI multiplexing system has been fixed, involving the addition of a tri-state buffer on the DOUT of the MAX7317, and the addition of pull-up resistors on the open-drain outputs of the MAX7317 as well as the tri-state outputs of the CS pin demultiplexers for DSCS (#22)
• An unpopulated footprint for a right-angle through-hole header has been added to provide test points for a few signals not exposed over the backbone (#20)
• Indicator LEDs have been changed, and their brightnesses have been adjusted (#21)
• Various minor fixes & improvements to silkscreens, schematic symbols, READMEs, footprints, and decoupling capacitors (#9, #11, #22)

See #22 (comment) for archives of the BOM variants of this board.

ODSv1.0.0-BP-Jmpv0.2.0

Changes:

• Breaking change: DAC has been removed, and pin assignments for the digital I/O expander header have changed, including addition of a second MAX7317 on the header (#22)
• SPI multiplexing system has been fixed, involving the addition of tri-state buffers on the DOUTs of the MAX7317s, and the addition of pull-up resistors on the open-drain outputs of the MAX7317 as well as the tri-state outputs of the CS pin demultiplexers for DCS (#22)
• Indicator LEDs have been changed, and their brightnesses have been adjusted (#21)
• Various minor fixes & improvements to layout, schematic, READMEs (#22)

HMI Board Connector Change

Maintenance release for the ODSv0.2.0 stack, as a stopgap update until ODSv1.0.0 reaches feature parity with ODSv0.2.0.

This revised design replaces the 12-pin and 4-pin Pico-Lock connectors for the control panel with 8-pin and 6-pin Pico-Lock connectors, because 12 pin Pico-Lock connectors are not available in the next few months. This design also replaces a 3-pin connector with a 4-pin connector for the toggle switch, as it has two VCC pins which need to be separately powered. This design also adds a connector for an illuminated push-button.

Processing Plane Connector Change

Maintenance release for the ODSv0.2.0 stack, as a stopgap update until ODSv1.0.0 reaches feature parity with ODSv0.2.0.

This revised design replaces the 12-pin and 4-pin Pico-Lock connectors for the control panel with 8-pin and 6-pin Pico-Lock connectors, because 12 pin Pico-Lock connectors are not available in the next few months. This design also adds a 6-pin Pico-Lock connector for 5V MOSI-only SPI, intended to be used to control a LED matrix, as well as spring-cage terminal blocks for GPIOs 30-39 and GND.

Motion Plane Connector Change

Maintenance release for the ODSv0.2.0 stack, as a stopgap update until ODSv1.0.0 reaches feature parity with ODSv0.2.0.

This revised design replaces the 12-pin and 4-pin Pico-Lock connectors for the localization board with 8-pin and 6-pin Pico-Lock connectors, because 12 pin Pico-Lock connectors are not available in the next few months. This connector change also removes the interface to select the voltage level of signals from the localization board for level-shifting to 3.3V - it is now required to be at 5V logic for level-shifting to 3.3V.

HMI Board

The HMI board serves as a control panel for user input into the stack. The HMI board has connectors for a joystick, a focus knob, and a toggle switch, and it has two board-mounted potentiometers.

Motion Plane Connector Change

This revised design replaces the 16-pin connector for the localization board with a 12-pin connector and a 4-pin connector, and it also adds pull-up resistors between the connector pins and the input buffer on those pins.

Processing Plane Connector Change

This revised design replaces the 16-pin connector for the control panel with a 12-pin connector and a 4-pin connector.
