Ollie

Support & Documentation

Ollie Firmware and Hardware documentation is available on Github

Features and Specifications:

• optional: CAN/RS232/RS485 DB9 pluggable connector

• Isolated UART:

  • Two isolated UART ports (UARTA and UARTB)

  • Data Rate up to 12 Mbps1.8/3.3/5 V voltage levels (set by slide switch)

• Isolated CAN:

  • Based on CANable/CANtact open hardware

  • By default flashed with *dual firmware CANtact and Candlelight*, firmware is set by the DIP switch

  • Termination Resistor switch

  • ESD protection

• Isolated Power Supply:

  • 1.8/3.3/5 V output voltage(set by slide switch). Output voltage can set only before USB is plugged in, to prevent accidental level change (hackable in firmware)

  • Current-limited with auto-restart (~100m V drop at max current)

    • 5 V @ 200 mA3.3 V @ 300 mA

    • 1.8 V @ 300 mA

  • Reverse voltage protection up to 10 V

  • Reverse current protection

  • Reverse polarity protection

• Isolated downstream USB:

  • USB Type-A connector

  • Supports 1.5 Mbps (Low Speed) or 12 Mbps (Full Speed) USB devices

  • Current limited with auto-restart

  • Reverse current protection
