A new audio board for the RaspberryPi 400

I have just noticed this:

The DacBerry 400S is for sale at less then 20€ (+5€ shipping to Europe I guess) in their shop, while the 400M, wich has a stereo line input, doesn’t seems to be on sale.

Boards are using a Texas Instruments chip, the TLV320AIC3104.
Amazing how simple the device tree overlay is:

// Definitions for TLV DACberry400
/dts-v1/;
/plugin/;
/ {
	compatible = "brcm,bcm2835";

	fragment@0 {
		target = <&i2s>;
		__overlay__ {
			status = "okay";
		};
	};

	fragment@1 {
                target-path = "/";
                __overlay__ {
                        codec_1v8_reg: codec-1v8-reg {
                                compatible = "regulator-fixed";
                                regulator-name = "tlv320aic3104_1v8";
                                regulator-min-microvolt = <1800000>;
