In some of my projects, I use the Raspberry PICO (RP2040 or RP22350) with the TFT_SPI color display ILI9341 or ILI9488 / ST7735. They are cheap, and are available with Touch-Screen and SD-Card Slot. With the lib arduino-pico from Earlephllhower it's possible to use the ARDUINO IDE, Together with the great grafic library: tft_esp32 from Bodmer it's easy to develop also bigger projects on the development board. You have only to put the Display in the sockets (2.4", 2.8", 3.2" ILI9341 or 3.5" , 4.0" ILI94

On the board are placed 

- socket for the PICO RP2040 / RP2350 board
- sockets for TFT-SPI-Displays (2.8" to 4.0")
- socket for EEPROM 24LC64/265
- socket for Dual-DAC MCP4802 / MCP4812 / MCP4822
- socket for Quad-ADC MCP3004 / MCP3204
- 2 sockets  for Servos
- 4 sockets for rotary encoder and/or Potentiometer
- Mini bread-board  (17x10 pins)
- 1 reset-button
- 4 switch-buttons
- 4 sockets for LEDs
- power-supply over USBC
- positive voltage  +12V (max 1.5A )
- positive voltage   +5V (max 700mA)
- negative voltage   -5V (max 150mA)
- 
- sockets for +, ground ,-
- sockets for SPI and I2C
new: 
        Arduino-NANO Adapter with divider 5V/ 3.3V (testet with Nano 328P/328BP)
        Arduino-NANO Adapter without divider for 3.3V NANOs (not tested)
 
The display(s) and the DACs are fixed wired to SPI-0 :                            SPIO16=MISO,GPIO17=TFT_CS,GPIO18=SCK,GPIO19=MOSI, (DAC_CS not connected)

In the next days I will show here  some projects I have realized with (help of) the development board. 

on github new/ changed KiCad (9.01) layout and schematics also from the adapter
