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" to 4").

weeks? On the board are placed 

- socket for the PICO RP2040 / RP2350 board
- sockets for TFT-SPI-Displays (2.4, 2.8, 3.2" ILI9341 and 3.5, 4.0" ILI9488)
- socket for EEPROM 24LC64/265
- socket for Dual-DAC MCP4802 / MCP4812 / MCP4822
- socket for Quad-ADC MCP3004 / MCP3204 with voltage divider
- 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
- ext. 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 ( tested with ESP32-S3-Nano)
 
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) 

The SPI-Pins for  ADCs and the SD-Card are not connected, SPI-Pins on connectors.
  
In the next weeks ? 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 adapters.
