 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Our new board from the PIC32MZ2048EFH100I/PF. Operating voltage is from 6V to 12V. There is a voltage regulator for the 3V3 supply of the processor installed. Another 3V3 voltage regulator is available for the analog voltage. All port lines are routed to the pin header. For VGA applications, the 3 resistors and the 3 diodes are on board. A led for displaying the operating voltage and a heartbeat led is also installed, as well as a reset button. A connector for connecting the console via a USB link and for the Pickit is also available.   |

Congrats! To be sold (as a built board) ... at all? Who by? Price? John |

@rentner111 Looks interesting. What size is your PCB? Also - are you selling it? If so, how much (and what is included/excluded)? WW For everything Micromite visit micromite.org Direct Email: whitewizzard@micromite.o |

Not a criticism - just my 'input': Would be perfect if one short side had a USB (connected to a SMD PIC1455); and the other short side had a uSD socket  Your setup has ICSP on one side, and console on the other - so enough space could be saved for the above using a PIC1455. Hence my question regarding PCB size. Another question - is this 2 layer? Thanks for any response . . . . For everything Micromite visit micromite.org Direct Email: whitewizzard@micromite.o |

this looks like a very nice, simple design. any chance of seeing the schematic? also, will it be made available without any of the pin headers or reset switch fitted, so as to make it suitable for posting in a standard envelope? cheers, rob :-) |

Hello friends ! We are a group of 3 seniors (age = 60-74) who have been engaged in electronics privately and professionally for more than 45 years. We developed this board together and adapted it to our requirements. @JohnS We make the boards at "MULTI-PCB UK", the unit price for production of 10 pieces is: € 7,90.- @WW The boardsize: 67.25mm x 42.85mm with 2 layers. We know the version with the PIC 1455, it is very good, but we have different boards and projects (PIC170x28p, PIC170x44p, PIC470x64p etc.) with the same connections. As we also have several applications with switching power supply and mains voltage (220V) in operation, I would like to develop a 100% galvanically isolated USB-TTL converter compatible with all our projects. @ robert.rozee Attached is the circuit diagram. I hope to have answered all questions and wish you a nice day! Best regards from Tyrol - Austria! Wolfgang, Erwin(rentner111) and Günter 2018-03-02_202904_PIC32MZ_CPU_V1.pdf |

Thanks - but is that the price with the CPU and SMD devices fitted? I suspect not :) And if not, what is the fully-populated board cost? John |
||||
| WhiteWizzard Guru Joined: 05/04/2013 Location: United KingdomPosts: 2794 |
Blimey John - I think the snow has got to your head! This is the cost that the PCB house charges to make 10 unpopulated PCBs. Shipping (plus possible duty) is extra. You'll be lucky to get a single 100pin MZ for that price; let alone ten, plus all the other components, plus the PCBs, plus the labour to make/configure/test them. However, IF I am wrong about the costs then I'll take 10 immediately please for 7.90 euros  EDIT: and of course I'd expect free shipping to the UK too please (Tracked & Insured service of course).

@PicFan Forgot to ask the question that John is getting too - are you offering PCBs for sale (unpopulated and/or populated)? Great work . . For everything Micromite visit micromite.org Direct Email: whitewizzard@micromite.o |

Well no, I'm just re-asking what I originally asked (*) because the answer appeared wrong. (*) have a look further up the posts John |

@JohnS If we order 10 pcs of PCB, s at "MULTI-CP" in UK, will cost us 1pc. € 7,90! Only 1pc. unpopulated PCB. A set of components (all parts purchased from Farnell.at) costs us about € 42 - 45.- The cost of a finished, tested board I can not say that I would like to first discuss this with my friend (Erwin). @ww Yes, but I must still clarify with my friend and I will then tell it. Wolfgang. |

Well, I figured the built one could not be 7.90E (too low a price) but now a single PCB costing that?!! No worries. Too costly for me to consider bearing in mind what else is available. Why don't Microchip sell something like that, built, for about what Olimex charge??? John |

It is certainly a good question and a frustration. Compare STM who provide a wide range of basic boards ( the Nucleo range) for very good prices with even the top of the range STM32 Nucleo-144 development board with STM32F767ZI MCU only £17.93 at Farnell and this includes a full programming capability with attached ST-LINK programmer which also includes USB/UART capability so you can connect direct to the PC with absolutely nothing else needed. The only thing missing in their range for the hobbyist is a PDIP package otherwise I think it would be a no-brainer to move to their products. I have recently revisited the STM and got the latest MM software up an running on the STMF4 but haven't released anything as it is just another platform to support with no real upside. |

All the reasons you mentioned IS the upside. Who really cares if MMBasic is running on a specific chip. As long as it is easily available and the language stays compatible. For simple projects use the MX150/170 for more elaborate use whatever there is. The rPi is in my opinion the wrong candidate and the range from STM is the right one. Microblocks. Build with logic. |

The ST ones do look better. The software tools are normal, too :) John |

I am very interested on developing with STM32F4xx. In the last few years an immense range of products have been developed around STM32xxx, above all, STM it is a leader in products such as MEMs and Power Devices and other products. STM is investing in the IoT world creating dedicated products. matherph, Please Can you focus on STM32 + MMBasic? Thanks Antonio |

Another +1 for MMBasic on STM boards. There is a huge range of STM4 boards at very low prices with lots of Flash and Ram and other features. Stable ADC, DAC, CAN. No need for special programmers and most boards have USB interface as standard. https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20180303040715&SearchText=stm32f4+board Very large range of genuine STM factory development and evaluation "Nucleo" boards with separate ST-Link microcontroller programmer at ridiculously low prices. http://www.st.com/en/evaluation-tools/stm32-mcu-nucleo.html?querycriteria=productId=LN1847 Much more widely used than Microchip PIC32. By all means retain PIC32Mx170 DIP as a simple single chip platform, but for more advanced applications STMF4 is a better choice in my opinion. |

Interesting. http://au.element14.com/stmicroelectronics/nucleo-h743zi/dev-board-nucleo-144-cortex-m7/dp/2776646# shows them for $3.48 assuming i have the correct board. Doesn't seem right though. ChopperP ChopperP |
