Entered in to PCBWAY Raspberry PICO CONTEST
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 on skull, PICO boot button hole. Overall dimensions are smallest as possibly.
SWOT analysis
Strengths:
-no competition
-simple as passible
-cheap
-beautiful design (I'm shameless)
-qwerty keyboard
-HD IPS display
-circuitpython
-micropython
-arduino core
Weaknesses:
-my programing knowledge is limited
Opportunities:
-GUI learning tool
-native USB
-ETHERNET 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 micropyton
Threats:
-please write in comments, I am blinded by my enthusiasm
FEATURES:
-Smallest as possibly
-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 or mico SD card (same place, same GPIO not together)
TODO:
-add header for wiznet or another ethernet module
-more examples
Working software features (demo codes):
-circuitpython display example
-micropython display example
-arduino display example
-arduino keyboard example
