Hello All,

Have sent this and other issues to support but have had varying degree of response in the past.

Looking for a detailed and safe instruction on how to power the Huskylens with an external power supply.

I have been testing with a usb on the husky for power... but have intermittent communication issues as I suspect that no usb hub or charger seems to be able to provide a steady current for the device in facial recognition mode.

Note: I am connecting to a ESP-32 Wrover ESP-32 Dev-Kit-V1 Module via I2C protocol. Programming via Arduino IDE

I have tried several configurations.

One unit works flawlessly using the I2C protocol with this configuration:
HuskyLens "UART RX/TX" and Ground connected to ESP-32 I2C pins and Ground
Power is being supplied by the USB cable.
Can send and receive data with HuskyLens and am able to send this data over websockets to a custom application I have designed.

I have another station that I have made a custom PCB board for to eliminate prototype wires and breadboard issues.
Am powering the Huskylens, ESP-32 and other peripherals with a 5v 12amp power supply.
Everything else - Relays, Servos, Linear Actuators, Hall Sensors, 5v-3v Level Shifters, Switches, Leds work and function 100%
I cannot get the huskylens to connect in any way while powered with external power. (USB cable is disconnected)

Trimmed the dupont connectors to make better connection between the Huskylens and the PCB connectors, suspecting a poor connection. This did not help. (I tried two different HuskyLens units - no variant on result.)

Attempted to run the HuskyLens rx and tx through a 5v-3v Level shifter - That did not help (the signal levels read 3.7v from the Husky rx/tx wires) so I reverted to a direct connection.

I am pulling my hair out trying to make this work.

I have searched all forums and github resources intensively and studied all code for the Arduino library trying to determine the best method.

I am using the I2C protocol because I can get it to work in certain configurations with the ESP-32 Dev-Kit-V1.

I am a bit confused about the various references online about the exclusive use of Software Serial in the HuskyLens Arduino Library... Yet... I did not see reference to that in the current source code files. Can the Huskylens now use Hardware Serial? The ESP-32 has more than one Hardware Serial.

Hopefully somebody has experienced similar issues…

Thank you for any troubleshooting suggestion you can provide.
