Here are all the things I discovered in my attempt to get everything working on this board with ESPHome. Hope it helps someone if you learn something interesting please share back.
TTGO-Camera-Plus Module
ST7789 Display IPS Panel 1.3 Inch 260ppi 240x240 16-bit full color pixels
OV2640 V2.1 2Megapixel
MSM261S4030H0 I2S Mic
MPU6050 Accelerometer/Gyroscope Sensor
IP5306 Battery Management
PSRAM
Uncomment different parts of the code if you want to play with different features some won't currently work with everything.
The last thing I was trying to do was to display the camera feed on the display with an imgproxy docker as online_image only supports PNG currently. Got it displaying online images just not the camera feed (Currently crashes when you try to use interval to load images)
Voice Assistant works pretty good displays what you say on the LCD display etc.
