Ερ: Is it waterproofn

Ερώτηση από vanjamalec επί 2022-11-12 12:12:34

DrMichael According to the listing, it is IP65 waterproof. The unit I bought appears to have some sort of conformal coating over the solar panel so it should by OK protecting against lop pressure water ingress.

Ερ: I need it more amper 5a, 6a or 7a. models 1205 , 1206, 1207 is coming ?

Ερώτηση από BG351137505 επί 2022-10-17 06:54:32

DrMichael I'd suggest you ask Customer service this question. This forum directs queries to people who have bought this item so they can respond based on their experience. I can attempt to answer product related questions, but I cannot speak for BG on their stocking policy.

Ερ: Can it work as normal phone/text and as video phone with whatsapp?

Ερώτηση από BG521853934 επί 2022-08-25 07:29:38

DrMichael First, I only got this tablet two days ago, so I have limited experience with it. Second, I don't use it with a sim, just on Wi-Fi. Having said that, I'd expect it to work fine as a phone; I just prefer to use a smaller phone that will fit in my shirt pocket. Similarly, I don't use WhatsApp (I find their terms and privacy policy unacceptable) so I have no experience with it. Nevertheless, I can see no reason why it wouldn't work. I am sorry I can't be more helpful, but I am a bit of a privacy freak and one of those strange people that actually reads the terms of online services rather than just saying "agree".

Ερ: What colour does it display R, B, G, W?

Ερώτηση από KIRASE επί 2022-08-18 04:51:44

DrMichael These are available in red, green and blue. I have bought each version at different times over the past 2 or 3 years. As per the listing, this set is RED. If you'd like green or blue, I'd suggest waiting; they will probably be available when the next batch is stocked.

Ερ: Can this support 12v on the hv side?

Ερώτηση από VernonSA επί 2022-08-08 01:32:07

DrMichael Well the specification says 5V for the high voltage side, so the only safe answer is No. I certainly have never attempted anything above 5V. If you google the circuit of a level shifter, it is basically a very clever design that takes advantage of the MOSFET body diode. Seriously, take a look at the circuit, It's well worth the time looking! Also, circuit-digest have a good tutorial on how logic level shifters work If you need 12V, I'd suggest using a MAX232 or equivalent. They are designed for 5V to 12V level shifting. Hope some of this helps.

Ερ: what is the best library to use?

Ερώτηση από therealkarl επί 2022-07-18 18:50:28

DrMichael It's always hard to answer questions line "what is the best" because it depends on what you are looking for. in a library. I assume you are not an expert in embedded programming (since you are asking for advice), so I'd recommend you try the Adafruit library. Adafruit have been a long-time contributor to open source and deserve our support for that. They also code in "the Arduino way" so it should be familiar to most beginners. I am a professional programmer, so I tend to value things like a clean architecture, solid code and low technical debt. Inevitably that means I write my own libraries, but I wouldn't recommend that route to everyone.

Ερ: What is the maximum capacity it can hold in mah?

Ερώτηση από BG152528441 επί 2022-07-26 01:34:51

DrMichael I haven't yet received my unit so the following is just me general understanding of electronics. First, it depends on the capacity of the 18650s you put in. If they are, say, 3000mAH then the total nominal capacity is 48,000mAH over 16 cells at a nominal voltage of, say, 3,7V. Second, taking the capacity as 48,000mAH, and assuming, say 90% efficiency for boosting from 3.7V to 5V, you can expect around 32,000mAH effective capacity at 5V. (48000*.9 x 3.7 ÷ 5). Hope this helps
