Re: ESP32-S3 DFU/Programming

ESP_Sprite, thanks.

I asked you because it seemed that you could help me understand.
Looks like there are no representatives of Expressive on this forum.

Re: ESP32-S3 DFU/Programming

ESP_Sprite, how can author use two CAN if ESP32 only has one TWI module?

1 × TWAI® controller, compatible with ISO11898-1 (CAN Specification 2.0)

Re: ESP32-S3 crystall ESR

Found in schematic "ESP32­S3­WROOM­2 Datasheet" for 32kHz:
ESR = Max. 70 KΩ

But what for 40 MHz?

Re: ESP32-S3 DFU/Programming

Why in your circuit not present 40 MHz resonator ?
As I see in DS:
"ESP32-S3 is unable to operate without an external main crystal clock."
