- RAM: DDR3 800Mbps. Default capacity is 256Mbytes.
- Flash: eMMC 4GBytes to 16GBytes (default 4GB), 8 bits data bus.
- Ethernet: onboard Physical (ready to use Ethernet 10/100Mbit link)
- USB: High speed USB OTG (OnTheGo)
- USB: High speed Host
- TFT CMOS/LVDS interface
- Wi-Fi+Bluetooth (option): b/g/n with u.FL antenna (BCM43438 chip), BT 4.1 (Low Energy compatible)
- Only one external supply of 3.3V required.
- Mechanical dimensions: 67.6 x 30 mm
- Connectors: SODIMM 204 pins
Resources
Workaround
- When you get that kind of error at Wi-Fi initialisation:
brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50
- You can try to unload/reload the driver:
# modprobe -r brcmfmac # modprobe brcmfmac [ 1881.792273] brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0: Aug 29 2016 20:48:16 version 7.45.41.26 (r640327) FWID 01-4527cfab [ 1881.850588] brcmfmac: brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30)
