Raspberry Pi Zero W was launched in February 2017 for $10 as an update to RPi Zero adding WiFi and Bluetooth connectivity. The Raspberry Pi foundation has now announced a new model called Raspberry Pi Zero WH.
What does not extra H mean? H Bridge? nope. Hybrid? nope. WH like in white PCB? re-nope. H means the 40-pin header is soldered. It can be more convenient for people who don’t own a soldering iron, or don’t feel confident soldering on their own.
- SoC – Broadcom BCM2835 ARM11 processor @ 1GHz with VideoCore IV GPU
- System Memory – 512MB RAM
- Storage – microSD slot
- Video Output – mini HDMI port and composite video (via 2 unpopulated pins)
- Connectivity – 802.11 b/g/n WiFi and Bluetooth 4.0
- USB – 1x micro USB OTG port, 1x micro USB port for power only
- Camera – 1x CSI camera connector
- Expansion – Soldered 40-pin HAT-compatible header
- Power Supply – 5V via micro USB port
- Dimensions – 65mm x 30mm x 5mm
This will be convenient for pHat boards, but the foundation also mentioned GPIO expander tool to use Raspberry Pi Zero (W/WH) with a PC running Debian, or other projects where you may not want to permanently solder wires, e.g. for prototyping with a breadboard.
No price was mentioned in the blog post, and few approved resellers have stared to list the new model, but I could find it on Pimoroni, where it is sold for 11.04 GBP excluding VAT (~$15 US), and for reference the shop sells RPI Zero W for 8 GBP exc. VAT (~$11 US), so you pay around $4 to get the version with the soldered header.
