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

Parts¶

• LM386; DS ; page 10

MCU¶

• STM32F042G4U6; UFQFPN28; 16KB; hab ich noch 17
• Get rid of an STM32F072 in order to have DAC?
• STM32G431KBU6

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
