Both screens work very well and the package is exceptional value for money. Arrived on time and well packaged Took me awhile to get them working. A few tips which may help? Download and use the MCUFRIEND libraries. MCUFRIEND_kbv-2.9.9-Release 2.8" screen (blue PCB) : Identifier and driver 0x6809. Touch screen pins XP=7,XM=A1,YP=A2,YM=6 My calibration int TS_LEFT=932,TS_RT=164,TS_TOP=156,TS_BOT=922 2.4" screen (red PCB): Identifier 0x0000. You need to force the identifier/ID to be 0x9341 On mine the text came out mirrored. Need to edit the MCUFRIEND_kbv.cpp file Find case 0x9341 (line2570 for me). In line 2571 add INVERT_GS. See line below lcd_capable = AUTO_READINC | MIPI_DCS_REV1 | MV_AXIS | INVERT_GS | READ_24BITS; Save the modified cpp file Use PORTRAIT_REV to get correct screen orientation (printed icons at the bottom) My Colours were in RGB (565) format and need changing to BGR e.g BLUE changes from 001F to F100. (5 most sig bits need to be least sig and visa versa. Middle 6 bits are OK). There may be a better way of doing this ? Touch screen pins XP=6,XM=A2,YP=A1,YM=7 My touch screen calibration: TS_LEFT=934,TS_RT=178,TS_TOP=212,TS_BOT=941; The touch screen mapping will probably need changing to get the correct directions of movement. Where required swap x and y and or left and right values.

Q: Using built-in firmware, picture was a mirror image ?

Saltus The hardware comes preloaded software, programmed by ESP-IDF. It is an application to run Wi-Fi camera. The output image is size 600*800, since it's 2-Maga camera, you sure can optimize the software to output the maximum size of photos.

emersok Isthere any information on how to communicate with the board ?

Lots of features including onboard MCU to give serial comms instead of slightly cryptic i2C interface means this module can be used "stand alone" connected to serial to USB adaptor and PC which is a plus. Be aware that lidar module is designed for manufacturer use and is not super easy to calibrate and tune. Lidar itself is TINY (grain of rice tiny) and needs to be handled with care - protective cover is recommended but then requires additional calibration and precautions to prevent internal reflections. All in all you will spend quite a but of time compared to ultrasonics to get this working for ranging - probably overkill for simple robotics projects. Very cool but very expensive and fiddly.

Very neat little unit which works well. Base I2C address can be re-programmed. Gives accurate distance measurements and very useful where space is limited. Smaller field of view than sonar so good alternative where longer ranges are not required
