As far as I can read, few new hardware updates will come from the Raspberry Pi Foundation in a couple of years, but yesterday we could see a slight renewal of one of the most popular boards due to its price: Raspberry Pi Zero W now comes With WiFi + Bluetooth for about $10...
1GHz, single-core CPU with 512MB RAM
Micro-USB On-The-Go port & Micro-USB power
HAT-compatible 40-pin header
CSI camera connector
802.11n wireless LAN & Bluetooth 4.0(Cypress CYW43438 as Raspberry Pi 3)
20 mA more than the Zero: 0.6-1.2W (120-230mA at 5.19V)
Raspbian compatible (sudo apt-get -y update && sudo apt-get -y dist-upgrade)
