Turn a Raspberry Pi into a device to browse an offline version of Wikipedia with a E-ink screen.
Inkplate
- Follow the steps to install the drivers for Arduino:
Get started - Download the Inkplate library:
e-radionicacom/Inkplate-Arduino-library - Flash the Arduino code in the
slowiki-inkplatefolder into the Inkplate.
It consists of a modified version of:
e-radionicacom/Inkplate-Arduino-library/Inkplate_Peripheral_Mode.ino
Official documentation for peripheral mode commands from the Inkplate developers:
Inkplate Peripheral Mode
Keyboard
Follow the instructions in the slowiki-30-keys-keyboard folder
slow-wiki/slowiki-30-keys-keyboard
PiSugar Pro setup
Follow the official guide:
PiSugar2-Pro Wiki
Remember that when the access point is enabled the address of the webUi will be 192.168.1.1:8421
Node app
- Copy the
rpi-nodefolder - cd into the folder
cd rpi-node - Install the dependencies
npm i
Kiwik-server
Follow this guide:

Stop the WAP
In case you need to use the wifi from the Rpi you need to disable the wireless access point
- Stop and disable the hostadp and dnsmasq services:
sudo systemctl stop hostapd dnsmasq
sudo systemctl disable hostapd dnsmasq - Edit the dhcpcd.conf file:
sudo nano /etc/dhcpcd.conf - Comment out the lines related to the static IP address
interface=wlan0
static ip_address=192.168.1.1/24
nohook wpa_supplicant - Reboot
sudo reboot
Restart the WAP
When you need to restart the wireless access point
- Stop and disable the hostadp and dnsmasq services:
sudo systemctl start hostapd dnsmasq
sudo systemctl enable hostapd dnsmasq - Edit the dhcpcd.conf file:
sudo nano /etc/dhcpcd.conf - Uncomment out the lines related to the static IP address
interface=wlan0
static ip_address=192.168.1.1/24
nohook wpa_supplicant - Reboot
sudo reboot
Boot on startup
- Edit the .bashrc file:
sudo nano .bashrc - Add the start command at the end of file:
cd /home/pi/rpi-node
node app.js - Set in Raspberry Pi configuration panel:
Boot: To CLI
Auto login: Login as user 'pi' - Reboot
sudo reboot
Revert boot mode
- Stop the node app
⌘ Command + C - Revert the Boot mode to display:
sudo raspi-config
System options -> Boot / Auto Login: Desktop Autologin - Reboot
sudo reboot
When reverting the Boot mode to display it will give error, stop all the node processes:
pkill node or pkill nodejs

Questions
How big is the Wikiboard PCB?
It measures 137.4 × 44.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wikiboard use?
47 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Wikiboard KiCad files?
From the danieledep/slow-wiki repository on GitHub, at the commit this page was made from: the board is slowiki-30-keys-keyboard/hardware/v1.0/wikiboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wikiboard design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
