Support & Documentation

Ollie Firmware and Hardware documentation is available on Github

Features and Specifications:



  • 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

    • ESD protection

  • Isolated RS485:

    • Bias and Termination resistors switches

    • Error-free transmission up to 500 kbps

    • ESD protection

  • Isolated RS232:

    • Typical data rate of 235 kbps

    • RS232 TX/RX voltage level ±12V. RS232 RX Absolute Max ±25V.

    • ESD protection
