Question: What is DiP-Pi?
Answer: The DiP-Pi is line of products that support rapid idea prototyping/developing without extensive needs for soldering or breadboarding, based on Raspberry Pi PICO.
Question: How many DiP-Pi are available?
Answer: Currently we have available 10 different DiP-Pis, but the list is extremely fast increasing. If anyone has an idea that would be interesting also for others, can share with us and we will implement it on a new DiP-Pi.
Question: OK. I found DiP-Pis that are covering my idea implementation, I implemented it, and it is working well, what next?
Answer: If designed application fulfills required needs; after successfully testing, user has 3 options:
• it is possible to use selected and tested DiP-Pi(s) set and use them as they are for the application.
• design the hardware by himself based on selected and tested DiP-Pi(s),
• or ask our company to design a single PCB (and if needed manufacture) based on tested DiP-Pi(s) set
Question: What headers on DiP-Pi exist?
Answer: There are 3 types of DiP-Pi headers:
• male (top-end),
• Stack female (stack),
• or stack female-male (Pass-Through) for stacking of more DiP-Pis.
Question: What are the dimensions of the DiP-Pi?
Answer: We made all DiP-Pi compatible with Raspberry Pi PICO, and have implemented two types of sizes 21x51mm and 65x51mm
Question: Are the DiP-Pis compatible between themself?
Answer: Yes, we done our best to keep compatibility in PICO peripherals usage, so user can stack them easy.
Question: Are the DiP-Pi compatible with other PCBs for the PICO?
Answer: We cannot guarantee it, but in most cases should as far be follows the Raspberry Pi PICO dimensioning and Raspberry Pi guidelines.
Question: I made an application based on DiP-Pi in QTY 2, I will need a case for that, is there any simple solution?
Answer: Yes, we developed a buildup case able to grow up slide by slide according to dedicated application.
DiP-Pi Power-Battery-WiFi Master (DiP-Pi PBW)
Question: What is the DiP-Pi PBW?
Answer: This is our first DiP-Pi and is covering the most critical parts needed of the Raspberry Pi PICO applications developments. They are:
• Extended Cable Powering
• Battery Powering and charging
• ON/OFF functionality
• and WiFi networking
This set of functionalities has been implemented on a single PCB with identical footprint of the Raspberry Pi PICO, assembled on various configurations.
Question: What versions are available of the DiP-Pi PBW?
Answer: It could be ordered as pure cable powering device only, with or without battery charger; or as a complete system with WiFi, or finally as WiFi only. The available versions are:
1. Cable Powering system from 6-18 VDC with Reset and ON/OFF – Powered via EPR or PICO USB
2. Battery Powering system with charger, Reset and ON/OFF – Powered via PICO USB
3. Cable and Battery Powering System with Reset and ON/OFF – Powered via PICO USB, EPR, with Battery Powering (also as back-up)
4. Cable and Battery Powering System with Reset and ON/OFF – Powered via PICO USB, EPR, with Battery Powering (also as back-up) with WiFi Connectivity.
5. Only WiFi Connectivity with ON/OFF and reset switch – powered via PICO USB only
Question: What is the charger maximum current?
Answer: The implemented charger can charge battery with current up to 1000 mA, however with resistor it has been set to 500 mA. User can change this resistor (if has soldering capabilities) to another value.
Question: What is the maximum current able to be supplied if system is powered via 6-18VDC EPR input?
Answer: It is 1500 mA @5V
Question: What is the ON/OFF capabilities, and can I switch OFF also the USB Powered PICO?
Answer: The slide switch implemented on the DiP-Pi allows to switch ON/OFF on all power sources EPR (6-18VDC), Battery as also USB.
Question: What is the RESET Button?
Answer: The RESET button is missing in the Raspberry PI PICO, so it has been implemented on DiP-Pi and connected directly to the PICO Reset pin.
Question: Can I have connected both cable power sources (EPR and USB) at the same time?
Question: What about battery back-up?
Answer: Battery powering has been implemented mainly for low power application. Connected battery can be LiPo or Li-Ion chemistry and should have implemented protection PCB. The
implementation of powering in the DiP-Pi is allows to automatic switch to battery powering when cable powering is absent and beck to cable when available again (simplified UPS).
Question: Why the EPR Cable powering has been selected to be 6-18V DC?
Answer: It is because need to cover application powered by Car Installations as also to support Solar Panels (most of them are 18VDC).
Question: Can I measure EPR level as also Battery Level?
Answer: Yes, you can use embedded A/D pins on the PICO. Both has been protected.
Question: Can I use these pins for other applications?
Answer: As DiP-Pi PBW is delivered to customer – NO. However, A/D pins on the are bridged with 0R 0402 resistors so user can easily remove them with soldering tip and then these A/D
pins are available for other applications. ON such case user will lose ability to measure the EPR and Battery level.
Question: Why has been not used other method of measure of EPR and Battery levels that would keep PICO A/D pins free (i.e. I2C A/D converter)?
Answer: As the Raspberry PI PICO is ultra-low cost, our care ware to keep costs extremely low.
