PIMORONI Badger 2040 W + mini Keyboard case

thingiverse

[ PIMORONI Badger 2040 W + mini Keyboard case ] - This thing makes a small console with a Pimoroni Badger 2040 W and a small keyboard. I made this thing for "Pimoroni Badge 2040 W (Badger 2040 seems to be applicable to this thing too)" and "M5Stack CardKB" - The "M5Stack CardKB Mini Keyboard Programmable Unit (MEGA328P)" I used for this thing is already EOL. The "M5Stack CardKB Mini Keyboard Programmable Unit V1.1" currently on sale would be applicable to this thing. - CardKB is not supported by Badger OS of Badger 2040/W. You have to prepare a program to control the i2c keyboard (address 0x5F). - Since this keyboard occupies the i2c (Qwiic) connector, other i2c devices cannot be connected, so it is convenient to have an i2c connector branch item such as "M5Stack 1 to 3 HUB Expansion Unit". - The parts of this thing are combined and joined together. Their fit is probably tight. If it is difficult to assemble, please take measures such as thinly shaving some of the parts. ----- [Requirements] PIMORONI Badger 2040 W (Pico W Aboard) https://shop.pimoroni.com/products/badger-2040-w or PIMORONI Badger 2040 https://shop.pimoroni.com/products/badger-2040 M5Stack CardKB Mini Keyboard Programmable Unit (MEGA328P) ...[EOL] https://shop.m5stack.com/products/cardkb-mini-keyboard or M5Stack CardKB Mini Keyboard Programmable Unit V1.1 (MEGA8A) https://shop.m5stack.com/products/cardkb-mini-keyboard-programmable-unit-v1-1-mega8a Grove to STEMMA QT / Qwiic / JST SH Cable - 100mm long https://shop.pimoroni.com/products/grove-to-stemma-qt-qwiic-jst-sh-cable-100mm-long Adafruit 3 x AAA Battery Holder with On/Off Switch and 2-Pin JST https://www.adafruit.com/product/727 [Optional items] M5Stack 1 to 3 HUB Expansion Unit https://shop.m5stack.com/products/mini-hub-module and some Grove/Qwiic - Grove/Qwiic cable (and i2c device[3.3V power and signal]) ----- - CAD File bdr_ckb_006e.stp [ STEP file ] - STL files base06e.stl ==> Updated(2023-9/9) ==> base103.stl clip06e.stl ckbbase06e.stl ckbplate06e.stl ----- [ Update: 20230909 ] The case shape has been modified to accommodate the addition of an SD card module and to hold the battery case.

A module with a micro SD card slot on 18x18mm board would be suitable. You may want to look for one that is the same size or smaller. What was used in this thing was... https://store.shopping.yahoo.co.jp/orangepicoshop/pico-m-031.html The pin assignment is below. uSD SPI / RasPicoW MISO ... GP16 SCLK ... GP18 MOSI ... GP19 SDCS ... GP9 (or Other unused GPIO on Badger2040W) (It will be required that the data line is pulled up with 10KΩ.) PIMORONI INKY FRAME's SD test program will work with a few changes. https://github.com/pimoroni/pimoroni-pico/blob/main/micropython/examples/inky_frame/sd_test.py (Change SPI CS from GP22 to GP9)
