Pi-BB-RPS Breadboard with RPS and DC-DC Converter Built-in

  • Pi-BB-RPS offers a lot of capabilities. It has two power-in sources: DC 7V to 24V (via the terminal block) and the micro-USB power port. It also provides a breadboard with a power bus for soldering your own components.
  • Ideal for powering a Raspberry Pi using a solar panel. See attached app note.
  • Power switches over from one power source (e.g., solar panel) to another (e.g., battery power pack) when power failure on anyone’s power source is detected (e.g., sunsets).
  • GPIO 21 on the Pi indicates which power source is active. GPIO 21 = 1 indicates DC 7V to 24V power supply is in use. GPIO 21 = 0 indicates USB power supply in use.
  • Provides 5V USB power out (max 2.5A). USB power out is the RPS power and can be used to power other devices. In addition, 3.3V/700mA power out is available via a terminal block to power 3.3 V devices. 3.3V is independently generated on the Pi-BB-RPS board, offloading the 3.3V power supply on the Raspberry Pi.
  • Dual-layer breadboard offers 25 columns x 10 rows or a total of 250 connect points. Five connection points are available for each column, for a total of 50 columns—ideal for connecting breakout boards such as a Real-Time Clock (RTC), etc.
  • Includes a 40-pin Raspberry Pi header.
  • Includes a mirrored header with solder points. Allows access to all 40 pins on the Pi.
  • USB Power powers everything – 5V bus as well as 3.3V bus.
  • Use an older power adapter you have (e.g., 12V power or a computer power adapter @ 19V) to power a Pi. Use an older power adapter AND the existing power adapter to power the Pi.
  • Use a solar panel and a battery bank to power the Pi. Use a battery bank to move the Pi around without having to reboot it.
  • Use the breadboard to attach Real Time Clock, GPS module, or other breakout boards to the Pi.
  • The maximum current for the DC-DC converter power source and the Pi-BB-RPS board is 2.5A.

NOTE: If the load is over 2.0 A, we recommend using forced air (e.g., a fan) for cooling. Ensure the ambient temperature is cool enough or air flows over the inductor, removing the heat for the PI and the components on the Pi-BB-RPS board.

Soldering required.

Alchemy Power Inc. (now a part of GP Consulting Inc.) has created HATs and boards for the Raspberry Pi. Irrespective of the type o Pi or a Pi clone, we conform to the 40 pin header definition set by the Raspberry Pi foundation. All our boards work across different models of the Pi (subject to current demands by different versions of the Pi). Like Apple, we design, test, build prototypes in the USA. The final production is done in China or other countries to provide maximum value to our customers.
