小弟現在不認為Apple M1 是個好選擇，改供電不易，不支援I2s。
樹莓派電路簡捷，可用GaN，ARM64就夠強捍了！
剛剛看到這個能夠支援 CM4 和 NVIDIA Jetson Xavier NX 的子版：

2018 年推出的 12nm Carmel：

基本上是買不到 399 鎂的官方開發板，淘寶只有這一位賣家比較有良心：

Jetson Nano 能夠支援樹莓派專用的 DAC HAT，理論上 Jetson Xavier NX 該沒有問題吧：

•40‑pin expansion header: Lets you connect a Jetson developer kit to off-the-shelf Raspberry Pi HATs (Hardware Attached on Top) such as Seeed Grove modules, SparkFun Qwiic products, and others. Many of the pins can be used either as GPIO or as “special function I/O” (SFIO) such as I2C, I2S, etc.
DC 輸入是 9V 至 19V 的，因此可用 GaN 和 PD 誘騙器供電。


官方的 Ubuntu 要明年才支援 kernel 5.10：

看來 352.8KHz 或以上的核心頻率還是有可能的。
