These are new to me, but here’s a brief document on setting them up. The Raspberry Pi Zero W:

Dimensions: 65mm × 30mm × 5mm

| SoC | Broadcom BCM2835 |
| CPU | ARM11 running at 1GHz |
| RAM | 512MB |
| Wireless | 2.4GHz 802.11n wireless LAN |
| Bluetooth | Bluetooth Classic 4.1 and Bluetooth LE |

I got this kinda cool [USB combo case](https://www.amazon.com/gp/product/B07NKNBZYG) that allows you to use it dual sided (!), that is either side can be inserted into the USB port for power, and in _theory_ you can SSH in over USB:

I ran into trouble with the GPIO pin headers, they require soldering. I’d prefer.. not.. to solder so I bought these pressure mount GPIO pin headers instead

> **[GPIO Hammer Headers - Solderless Raspberry Pi Connectors](https://www.adafruit.com/product/3413)**
>
> If your soldering isn't quite up to scratch, or you just don't own a soldering iron yet, then these nifty hammer headers from Pimoroni might be just what you need. They come in ...

I got confused because the “regular” Pis have these headers already pre-soldered on, but apparently that’s not the case on the Pi Zero. EDIT: there is a distinction between the Pi Zero W and the [Pi Zero WH](https://shop.pimoroni.com/products/raspberry-pi-zero-wh-with-pre-soldered-header) – which has the headers pre-soldered. That’s what you want, if you need the headers!

So basically what you need is:

- Pi Zero W (make sure it’s the 2017 wifi enabled model)
- the “hammer” GPIO connector set that you can pressure mount on
- quality 32gb SD card

I do have these two pi-zeros set up and running:

The official way to set them up is via SSH over USB per the wiki:

[https://wiki.52pi.com/index.php/USB\_dongle\_for\_Raspberry\_Pi\_Zero/Zero\_W\_SKU:EP-0097](https://wiki.52pi.com/index.php/USB_dongle_for_Raspberry_Pi_Zero/Zero_W_SKU:EP-0097)

- Download [the latest Raspbian image](https://www.raspberrypi.org/downloads/) 32-bit
- Flash your SD card as usual
- Open up the `boot` partition and edit `config.txt`, adding `dtoverlay=dwc2` to the bottom
- Open up `cmdline.txt` and add `modules-load=dwc2,g_ether` after `rootwait`
- Create a new file named `ssh` in the boot folder
- Insert this TF card to Raspberry Pi Zero/Zero W
- Pop your newly set up SD card into your Pi Zero
- plug it into a USB port and you should be able to SSH in to `raspberrypi.local`,
- you will need Bonjour, iTunes or Quicktime installed in Windows or Avahi Daemon in Linux for this to work.

I couldn’t get the last bits to work in Windows 10, though I definitely made edits to the relevant files in the filesystem:

### `cmdline.txt`

`console=serial0,115200 console=tty1 root=PARTUUID=c2eb13c4-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait modules-load=dwc2,g_ether`

### `config.txt`

```

It says **you will need Bonjour, iTunes or Quicktime installed in Windows or Avahi Daemon in Linux for this to work** and I installed iTunes in Windows 10 but still had no luck getting in via local SSH.. the `raspberrypi.local` address could not be resolved.

What I _did_ get to work is [setting up wifi access](https://www.raspberrypi-spy.co.uk/2017/04/manually-setting-up-pi-wifi-using-wpa_supplicant-conf/). Create a blank text file named `wpa_supplicant.conf`. Use a plain text editor rather than a Word Processor.

### `wpa_supplicant.conf`

```auto
country=us
update_config=1
ctrl_interface=/var/run/wpa_supplicant

network={
 scan_ssid=1
 ssid="MyNetworkSSID"
 psk="Pa55w0rd1234"
}

```

(Oh and I also created the blank `ssh` file in the root so SSH was enabled.)

I copied that `wpa_supplicant.conf` file to the SD card in the root, plugged in the USB power, let it boot up, and voila.. it showed up with a valid IP address:

I got a pressure mount hat from here, because I _suuuck_ at soldering.

> Absolutely no soldering required! All that's needed is a few gentle taps with a hammer and bazinga! Your header is securely attached to your Pi Zero or pHAT.

Pressure mounting is a bit finicky so you have to eyeball it and make sure all the pins are more or less at the same depth.

(I also belatedly realized the [Raspberry Pi Zero WH](https://www.amazon.com/dp/B07W3GJTM1/) includes the soldered-on headers for a few more bucks, $18 vs $27, I should have just done that in the first place! I also noticed this stuff is a bit more expensive on Amazon versus the “official” vendors like Canakit)

The e-ink display docs are here, and they work. I skipped the Python 2 stuff though.

> **[2.13inch e-Paper HAT (B) - Waveshare Wiki](https://www.waveshare.com/wiki/2.13inch_e-Paper_HAT_(B)?Amazon)**

(click on “hardware / software setup” tab at the top, scroll down to the Raspberry Pi section)

This e-Ink module is marked V3, rev 2.1, and I _think_ 4 line SPI?

 ![image](https://discourse.codinghorror.com/uploads/default/original/3X/a/9/a94339e4aabfd12da8b9cef6468bcfc2c844ba7f.jpeg)

so the example python file I used included V3 as well as the dimensions of 2.13 inch. After some pressure mount pin nudging, I got both to work!

If you had bet me a thousand dollars when I woke up this morning that I’d be reading the sentence

> I installed iTunes in Windows 10 but still had no luck getting in via local SSH

I would have called you a fool and taken it gladly. (How on _earth_ is Bonjour/iTunes providing USB/serial SSH? And _surely_ there has to be a non-Apple solution for that problem… right?)

ETA: also, I just did my own Pi setup this weekend with an old 3B I had lying around, turned it into a custom DHCP server so I could feed Smart DNS settings to my Rokus. What’s your plan with the e-ink displays? They look really neat!

Try `raspberrypi.lan` instead of `raspberrypi.local` - that worked for me for SSH from Win 10 to a Pi3 with Raspberry Pi OS last month.

Hey! Thanks for the nudge! That did work! 🥳

I used Powershell this time, and note that I changed the name (via `raspi-config`) of each so that I could keep track of them:

- pizero-a
- pizero-b

I have no idea why @thw0rted but the docs page said iTunes might be required (Bonjour?). What can I say, I was desperate.. I’ll uninstall that now..

Just FYI, in case this happens to someone else: the SSH via PuTTY to rasperrypi.local worked for me, but my password kept getting rejected, and it was only after a while that I realized that I had been logging in to the wrong raspberry pi (I have dozens of them, albeit none with USB connection; it seems the .local also works with locally LAN connected Pi’s as well). I changed the hostname with sudo nano /etc/hostname and then used the unique hostname to try again, and then it worked!
