Its onboard peripherals include two USB Type-C ports (1 device, 1 host) and RTL8189FTV WLAN. A MangoPi MQ-R variant of the board also exists. The MQ-R has a different form factor, but the onboard peripherals are the same. Most D1 and D1s boards use a similar power tree, with the 1.8V rail powered by the SoC's internal LDOA, analog domains powered by ALDO, and the rest of the board powered by always-on fixed regulators. To avoid duplication, factor out the regulator information that is common across boards. The board also exposes GPIO Port E via a FPC connector, which can support either a camera or an RMII Ethernet PHY. The additional regulators supply that connector.
