#2This chip looks similar to the F1C100s that was used in the $3 Linux business card: https://www.thirtythreeforty.net/posts/2019/12/my-business-c...
By switching to RISC-V I guess Allwinner can save a few cents of Arm license fees.

#3That's not much DRAM, but consider that the Funkey S (https://www.kickstarter.com/projects/squonk/funkey-s-the-wor...) uses the Allwinner V3s (32b ARMv7-a) with 64MB DDR2 DRAM.

#4The HDMI and DSP lines are crossed out. Does anyone know of they aren't supported on this chip vs the regular D1?

Likely a mistake in the spec list copied from the earlier intro article published in March. The chip has no DSP, HDMI or DVI blocks listed so it makes sense.

Might be that they care about open computers.

Maybe but from the way they violate the GPL license and keep distributing binary blobs for their hardware I'd go out on a limb and say the money angle is more likely.

Allwinner? Maybe, but I highly doubt it. They're one of the worst offenders when it comes to releasing sources.[0]

The second paragraph says:
> Besides the built-in RAM, Allwinner D1s comes with many of the same features as D1 RISC-V SoC, but loses HDMI output and the HiFi 4 audio DSP, and Allwinner made some tweaks to the IOs with one less I2S audio interface, and general-purpose ADC.

I doubt it. They have been found to be in violation of the GPL for years, ranging from media codecs to bootloaders. Their response, even after joining the Linux foundation, was to obfuscate the code to make GPL violations hard to find.
