'''The''' screen for ZeroPhone. Do keep in mind that there are different breakouts for this screen which mainly are different by pinouts, you will need the 6-pin "VCC-GND-SDA-SCL-CS-D/C" one ("SDA" is sometimes called "D0" or "MOSI", and "SCL" is sometimes called "D1"). There's a version that has "RST" pin instead of "CS", it might be cheaper but it won't allow SPI on the 13-pin expansion port to work properly, so if you want to use SPI on the 13-pin expansion port, avoid that breakout (it also has GND and VCC swapped, so make sure you connect this screen right if this is what you have to work with.)

A simple SIM800 breakout, doesn't give access to all the capabilities that SIM800 chips have, but still has pins that are the most important for ZeroPhone to work as a phone. Only analog audio is accessible, so that is what's used, with an analog microphone&speaker. The breakout has 12 pins, only 11 of those are soldered to the ZeroPhone board - 12th is an antenna pin, which, in addition to not being necessary (as ZeroPhone is supposed to use an u.FL-connected antenna), could probably decrease reception quality, because something something RF something something black magic.

This page is work-in-progress, not all the components are added - so don't yet use this page to make an order.

PCBs

The last stable PCB release is Gamma release, with files available [####### here].

Sourcing PCBs can be done from different sources. The PCBs you need are: 1. Front PCB: 4x10cm, 2 layers, 1.6mm, ##### 2. Back PCB: 4x10cm, 2 layers, 1.6mm, ##### 3. Keypad PCB: 4x6cm, 2 layers, ###mm, ##### 4. 18650 holder carrier board: 4x7cm, 2 layers, ###mm, #####

It doesn't matter that much whether PCBs have ENIG or HASL plating (though ENIG is the nicer option for soldering). The color of soldermask also doesn't matter as much.

Here are the suggested places you can get the PCBs from:

  • OSHPark ([##### front], [####### back], [######## keypad] and [######## 18650] PCBs). You get three copies of each PCB.
  • DirtyPCBs, Elecrow or #########. You get about 10 copies of each PCB.

If you're ordering from places where they have fixed-price 10x10cm panels and allow panelization (such as DirtyPCBs), you can [######## panelize your boards] to ######halve the cost of ordering, so, say, you won't spend $64 ordering 4 different boards, but only $32, ordering 2 panels with 2 boards on each. If you're ordering from places like OSHPark, though, that's not viable, since OSHPark charges by board dimensions.

Pi Zero

As of now, there are multiple resellers for Pi Zero - recently, about 30 more have been added. The site-to-go for looking up Pi Zero availability used to be whereismypizero.com, but now there's thepilocator.com , which has all the online resellers listed, so the latter is the recommended site to find a place to get a Pi Zero.

You can get either a Zero or a Zero W - the Zero W has Bluetooth and doesn't require ESP8266 (thus freeing some pins that can be used for mod boards). However, due to lots of metallic parts around Zero W antenna, WiFi range is slightly decreased, and Bluetooth is not yet supported.

Breakouts

1.3" SPI OLED screen

The screen for ZeroPhone. Do keep in mind that there are different breakouts for this screen which mainly are different by pinouts, you will need the 6-pin "VCC-GND-SDA-SCL-CS-D/C" one ("SDA" is sometimes called "D0" or "MOSI", and "SCL" is sometimes called "D1"). There's a version that has "RST" pin instead of "CS", it might be cheaper but it won't allow SPI on the 13-pin expansion port to work properly, so if you want to use SPI on the 13-pin expansion port, avoid that breakout (it also has GND and VCC swapped, so make sure you connect this screen right if this is what you have to work with.)

SIM800

A simple SIM800 breakout, doesn't give access to all the capabilities that SIM800 chips have, but still has pins that are the most important for ZeroPhone to work as a phone. Only analog audio is accessible, so that is what's used, with an analog microphone&speaker. The breakout has 12 pins, only 11 of those are soldered to the ZeroPhone board - 12th is an antenna pin, which, in addition to not being necessary (as ZeroPhone is supposed to use an u.FL-connected antenna), could probably decrease reception quality, because something something RF something something black magic.

GSM antenna for SIM800

If an external PCB antenna (like on the photo to the right, TODO: add photo) is not supplied alongside the SIM800 breakout you'll be getting, you'll also need to get an antenna separately, since the "gold-plated coil" antenna that's included by default doesn't fit the breakout as installed in ZeroPhone.

ESP12

It's important that you get the version that has 6 pins on the side opposite to the antenna (labeled "SCLK,MOSI,GPIO10,GPIO9,MISO,CS0"). ESP12-E or ESP12-F will fit ( -F is claimed to have better antenna and would be therefore preferred)
