# Keyboard Project ## Description A keyboard with 3 buttons and a knob. Keys have screens, the knob can turn and get pressed. (Rotary encoder.) It'll be multipurpose. So the end user could map the keys to different functions. We'll target functions in Flux. The screens might be left without function for the V1. To de-risk. We can follow up later with software to make them work.) + Some kind of microcontroller to read the values from the buttons and rotary controller. Transfer from USB to computer in a way the computer is happy with. ## Project Details - **Owner:** philipkyeswa - **Created:** 9/27/2023 - **Last Updated:** 1/3/2025 - **Visibility:** Public - **Forks:** 3 - **Copies:** 1 ## Key Components ### D1 — [LED](https://www.flux.ai/jharwinbarrozo/led-tht.md) - Forward Voltage: 1.70 - Emission Coefficient: 3.73 - Series Resistance: 0.42Ω - Saturation Current: 93.2e-12A - Breakdown Voltage: 0V **Pins:** - A [pin 2] - K [pin 1] ### D2 — [LED](https://www.flux.ai/jharwinbarrozo/led-tht.md) - Emission Coefficient: 3.73 - Forward Voltage: 1.70 - Breakdown Voltage: 0V - Series Resistance: 0.42Ω - Saturation Current: 93.2e-12A **Pins:** - A [pin 2] - K [pin 1] ### D3 — [LED](https://www.flux.ai/jharwinbarrozo/led-tht.md) - Emission Coefficient: 3.73 - Forward Voltage: 1.70 - Breakdown Voltage: 0V - Saturation Current: 93.2e-12A - Series Resistance: 0.42Ω **Pins:** - A [pin 2] - K [pin 1] ### MT1 — [PEC11R-4215F-S0024](https://www.flux.ai/adrian95/pec11r-4215f-s0024.md) - Datasheet URL: https://www.bourns.com/docs/Product-Datasheets/PEC11R.pdf - Manufacturer Name: Bourns Inc. - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Sensor - Manufacturer Part Number: PEC11R-4215F-S0024 **Pins:** - 1 [pin 1] - 2 [pin 2] - A [pin A] - B [pin B] - COM [pin COM] - SHIELD [pin S1] - SHIELD [pin S2] ### SW1 — [MX1A-11NW](https://www.flux.ai/adrian95/mx1a-11nw.md) - Manufacturer Name: Cherry Americas LLC - Part Type: Switch - Datasheet URL: https://media.digikey.com/pdf/Data%20Sheets/Cherry%20PDFs/MX%20Series.pdf - Manufacturer Part Number: MX1A-11NW **Pins:** - 1 - 2 ### SW2 — [MX1A-11NW](https://www.flux.ai/adrian95/mx1a-11nw.md) - Manufacturer Name: Cherry Americas LLC - Datasheet URL: https://media.digikey.com/pdf/Data%20Sheets/Cherry%20PDFs/MX%20Series.pdf - Part Type: Switch - Manufacturer Part Number: MX1A-11NW **Pins:** - 1 - 2 ### SW3 — [MX1A-11NW](https://www.flux.ai/adrian95/mx1a-11nw.md) - Manufacturer Part Number: MX1A-11NW - Datasheet URL: https://media.digikey.com/pdf/Data%20Sheets/Cherry%20PDFs/MX%20Series.pdf - Part Type: Switch - Manufacturer Name: Cherry Americas LLC **Pins:** - 1 - 2 ### U1 — [Raspberry Pi Pico Shield](https://www.flux.ai/jharwinbarrozo/raspberry-pi-pico-shield.md) - Manufacturer Part Number: Pico - Part Type: Microcontroller **Pins:** - 3V3 - 3V3_EN - ADC_VREF - AGND - GND - GND - GND - GND - GND - GND - GND - GND - GPIO0 - GPIO1 - GPIO10 - GPIO11 - GPIO12 - GPIO13 - GPIO14 - GPIO15 - GPIO16 - GPIO17 - GPIO18 - GPIO19 - GPIO2 - GPIO20 - GPIO21 - GPIO22 - GPIO26_ADC0 - GPIO27_ADC1 - GPIO28_ADC2 - GPIO3 - GPIO4 - GPIO5 - GPIO6 - GPIO7 - GPIO8 - GPIO9 - RUN - SWCLK - SWDIO - VBUS - VSYS *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/philipkyeswa/keyboard-project](https://www.flux.ai/philipkyeswa/keyboard-project).* --- *Generated from [https://www.flux.ai/philipkyeswa/keyboard-project](https://www.flux.ai/philipkyeswa/keyboard-project)*
