DiP-Pi Power Master FAQ
This is our third DiP-Pi based on the same PCB of DiP-Pi PIoT and is covering the most critical parts needed of the Raspberry Pi Pico Extended Powering developments. They are: • Extended Cable Powering 6V-18V DC • Battery Powering and charging • Automatic both ways UPS functionality on all Cable Powering sources (including Raspberry Pi Pico USB powering) • ON/OFF slide switch functionality on all Powering Sources (including Raspberry Pi Pico USB powering) • RESET Button • Embedded 1-wire interface • Embedded DHT-11/22 Humidity/Temperature Interface • Plenty of informative LEDs • Plenty of ready-to-use Micro Python and C examples.
The DiP-Pi Power Master is powered through the Raspberry Pi Pico micro–USB Plug, Battery and EPR Socket (6V-18V DC).
The DiP-Pi Power Master is a smart powering system to be used with Raspberry Pi Pico. It is automatic smart charger (optionally user controllable), Extended Cable Powering 6V-18V DC, micro–USB. With Battery Backup (UPS Functionality), and ON/OFF Slide Switch.
How can I switch ON/OFF the system (DiP-Pi Power Master + Raspberry Pi Pico) without removing the micro–USB Plug?
You can switch the system ON/OFF using Slide Switch placed on the DiP-Pi Power Master. This switch will also put to OFF the Raspberry Pi Pico even if it is still connected to the micro–USB Plug (by using the 3V3_EN).
Yes, you can use the ON/OFF Slide Switch as a Boot Mode initiator. This will save you from the very unhandy process of removing the micro–USB Plug from the Raspberry Pi Pico.
Battery powering has been implemented for low power application. Connected battery can be LiPo or Li-Ion chemistry and must have implemented protection PCB – the allowed max current should be not higher than 2A. Batteries with 1C factor are strongly recommended. The implementation of powering scheme in the DiP-Pi Power Master is allows to automatic switch to battery powering when cable powering is absent and back to cable when cable powering is available again (both ways UPS functionality).
The DiP-Pi Power Master is a subset of the DiP-Pi PIoT so the only missing pars are the related to the powering. You still have DHT-11/22 and 1-wire interfaces.
