Wed Jun 24 02:02:47 PDT 2026
The board consists of a CLRV1126F core module and a DLRV1126 carrier
board. The core module contains the RV1126 SoC, eMMC and RK809 PMIC,
while the carrier board provides Ethernet, SD card, AP6212 WiFi and
Bluetooth, PCF8563 RTC, ADC keys, GPIO LEDs and audio connectors.
The board has been tested with Ethernet/NFS boot, eMMC, SD card, SDIO
WiFi enumeration, Bluetooth LE scanning, RTC, ADC keys, GPIO LEDs and
RK809 audio card registration.
