The board features 1GB DDR3L, USB3.0 Type-C, USB HS Type-A, microHDMI, 16GB eMMC flash, 1G Ethernet, 802.11ac 2/5GHz, Bluetooth, and BeagleBone expansion headers. For more information, refer to: https://beaglebone.ai The corresponding patch against the mainline linux kernel can be found at: https://patchwork.kernel.org/patch/11254903/ This patch introduces the BeagleBone AI device tree. Note that the device use the "ti,tpd12s016" component which is software compatible with "ti,tpd12s015". Thus we only use the latter driver.
