Global SIM Card

The Global SIM Card Solution provides cellular coverage in 188 countries. The guide lists the supported countries and network operators.

The AutoPi Mini and TMU CM4 devices purchased with a subscription already include a SIM card. For other configurations, select a data plan from the AutoPi Shop. Monthly data usage is available in AutoPi Cloud.

DoIP HAT

The DoIP HAT adds Diagnostics over Internet Protocol (ISO 13400) support to compatible AutoPi TMU CM4-based devices. It supports Ethernet-based vehicle diagnostics, including UDS communication and ECU programming workflows.

Check vehicle compatibility

Install a DoIP-enabled device only in a vehicle that supports Ethernet diagnostics. After installation, the AutoPi Ethernet interface is routed internally to the vehicle and must not be connected to an external Ethernet device.

Follow the DoIP HAT installation guide.
Complete the DoIP software setup.
Purchase the DoIP HAT for AutoPi TMU CM4.
