Allwinner D1s (also known as F133) is based on a RISC-V core, and is a cheaper version of the D1 with the following differences:

  • 64 MB of DDR2 memory included in the same package, instead of requiring external memory.
  • No Tensilica HiFi4 DSP.
  • No HDMI output.
  • One less I2S port.

The D1s features a single RV64GCV[3] core XuanTie C906 from T-Head Semiconductor (subsidiary of Alibaba).
