h1. Eval
CANDis is quite silent.
CANBuz probably will have same issues. Need to test capacitors.
F=As/V
qalc 0,000022*3 = 0,000066 = 0,066mAs
Ich hab doch noch grosse
Is it the power regulator/LDO? What did i solder?
h2. Parts
* LM386; "DS":https://www.ti.com/lit/ds/symlink/lm386.pdf ; page 10
h2. MCU
* STM32F042G4U6; UFQFPN28; 16KB; hab ich noch 17
* Get rid of an STM32F072 in order to have DAC?
* STM32G431KBU6
h2. DAC
* Maybe later; SAI would be more interesting. DAC for testing DMA.
* 44,100 Hz
* Would require SPI flash for recorded sound
* Adjustable volume
* Solderbridge for fallback
