## Article

**DETAILS**

#### **#PICOmputer – World first Raspberry RP2040 PICO – QWERTY & IPS devkit**

```
I will permanently update features and description
by current development status ... now 
12.11.2021
+ updated to last revison Picomputer MAX
+ 2inch IPS display? 320x240 ST7789 for retro computer emulation?

25.4.2021
+ gerbers
+ extra project - Top front panel
+ schematic
+ shoot PCB
+ github repository "https://github.com/bobricius/PICOmputer"
+ display, keyboard GPIO definitions

12.5.2021
+ updated gerbers
+ fixed unconnected DEL button
+ much more labels
+ micro SD card "micro SD sharing postion and GPIO with RFM95"
??
19.5.2021
+ components list
??
TODO SW:
- RFM95 definitions
- KEYBOARD cursors keys
25.5.2021
+ some code examples on GITHUB?
12.6.2021
+ rounded PCB coners for less pocket destroy

TODO HW:
- add micro sd card -DONE
- add ethernet module header ... etc wiznet or anotner
- adjust frame position for display on module - DONE
???
```

I am take care to minimize external components, use maximum features integrated on PICO board: Power switch use enable input on PICO, ON-BOARD LED is visible thanks to missing solder mask, PICO boot button hole. Overall dimensions are smallest as possible.

**Front panel is as separated project**

<https://www.pcbway.com/project/shareproject/PICOmputer___front_panel.html>

**SWOT analysisS**trengths:

-no competition

-simple as possible

-cheap

-beautiful design **(I’m shameless)**

–**qwerty keyboard-HD IPS display – onboard-any display, iPS, TFT, OLED, eInk by wires, need just redesign front panel**

-circuitpython

-micropython

-arduino core

**W**eaknesses:

-my programing knowledge is basic

**O**pportunities:

-GUI learning tool

-native USB

-ETHENRNET possibility, there is big opportunity in application where is needed something like

networking plug and play … quick connect to LAN with DHCP configuration, etc. simple terminal

-standalone computer programmable in basic or micropython

**T**hreats:

-please write in comments,** I am blinded by my enthusiasmFEATURES**:

-Smallest as possible 100x65x8mm

-Absolute minimum components.

-Auxiliary USB-C for power only.

-Access to boot button

-bonus flashing eyes with internal led.

-IPS 240*240 display. 3 types or more

-Speaker

-free GPIO header

-Reset button

-power switch controlling internal buck-boost

-optional RFM95 LoRa radio

## **TODO**:**

### **–add adapter for wiznet or another ethernet module (waiting for module)**

-more examples

**Working software features (demo codes):**

-circuitpython display example

-micropython display example

-arduino display example

-arduino keyboard example

**Supported displays:**

-12pin st7789 IPS 240×240 via flex cable 1.3″ inch

-12pin st7789 IPS 240×240 via flex cable 1.54″ inch

-12pin st7789 IPS 320×240 via flex cable 2″ inch

-8pin st7789 IPS 240×240 via header

-any display with popular china module pinout GND,VCC,SCK,DAT,RES,DC,CS,BACKLIT

## **CODE EXAMPLES and DEFINITIONS**

```
  #define TFT_CS        17
  #define TFT_RST       21
  #define TFT_DC        16
  #define TFT_MOSI      19
  #define TFT_SCLK      18
  #define TFT_BACKLIGHT 20 //Display backlight pin 

  #define speaker       0  

byte colPins[COLS] = {1, 2, 3, 4, 5}; //connect to the column pinouts of the keypad extra cursor keys 14
byte rowPins[ROWS] = {6, 9, 15, 8, 7, 22}; //row pinouts of the keypad

char directKeys[ROWS][COLS] = {
  {KEY_RETURN, ' ', 'm', 'n', 'b',},
  {KEY_DELETE, 'l', 'k', 'j', 'h',},
  {'p', 'o', 'i', 'u', 'y',},
  {KEY_SHIFT, 'z', 'x', 'c', 'v',},
  {'a', 's', 'd', 'f', 'g',},
  {'q', 'w', 'e', 'r', 't',}  
};
```
