Good board, needs more documentation

For CAN32 - An ESP32 dev. board with CAN-Bus (V2.1)

The board is a good board so far. It needs to be better documented for the GPIO setup and the hardware. It took a long time to figure out there was a 120 ohm termination resistor on the CAN interface. A jumper (or option to order the board without it) would be much appreciated. At a minimum a photo showing where it is so it is easy to identify when trying to remove it.

EDIT: Of my two boards, they will not boot on 12V. Both boot from USB just fine.
EDIT 2: OK, I have figured out the issue with the 12V powering the board. If anything is being externally powered from the boards 3.3v pin, the ESP32 will fail to boot. Seems like an issue in the regulator not handling the inrush current. In my case I am only powering a 16mA opto-isolator, so well within what should be able to be handled. Without diving into the board's power delivery design, I am thinking something needs to be done to better handle the inrush current on boot to ensure stable voltage.

Hi Trevor,
Thanks for the review!
I will update the documentation with information about the termination resistor.

Dual CanBus Review

For Dual CAN-Bus adapter for Teensy 4.0, 4.1

This Dual Can-Bus for Teensy is excellent product and well made. I will say for the seller, he/she needs to communicate better though.

Great board

For CAN32 - An ESP32 dev. board with CAN-Bus (V2.1)

Would have appreciated more documentation but there wasn't anything surprising, my existing ESP32 code was ported over quickly with ease.

Finding a board with this exact set of features is difficult and I am pleased with the result.
The only things I would wish for is a lower consumption design and a mini SMP connector for a GPS external antenna.

#define LED_PIN 13
#define SD_CS_PIN 2
#define SD_MISO_PIN 19
#define SD_MOSI_PIN 23
#define SD_CLK_PIN 18
#define CAN_RX_PIN GPIO_NUM_4
#define CAN_TX_PIN GPIO_NUM_5
#define IMU_SDA 21
#define IMU_SCL 22

GPS is on UART2 default pins, upesy_wroom or esp32dev work for platformio

[env:can32]
platform = espressif32
board = upesy_wroom
framework = arduino

Great transaction and product.

For Dual CAN-Bus adapter for Teensy 4.0, 4.1

Well made and packaged product. Documented and complete.
Quick shipping too! Can't wait to finish my project with these.

All good!

For The Void Wallet()

Just as it was described in the photo. Seller shipped it pretty quick and I'm happy with it. Can be a bit difficult to get used to finding your cards in a wallet like this, but the main benefit is how slim it is. No more bulky pockets, and a very sleek (nerdy) design. Cheers :)
