 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. |

Hello, everyone! Everything will be based on modules with 2,54mm pitch and THT. This will be not that hard to solder!! Please share your thoughts and discuss pros and cons. I have a rough idea of what this might look like, but some details are still up in the air. I’d like to work this out over time. I plan to use KiCad for the carrier board and FreeCAD for the enclosure. As a first step, I’d like to assemble everything on a double-sided perforated board to get a feel for the best layout, and then design the PCB using KiCad from the start . To do this, first symbols/footprints for all the modules need to be created. First, here’s my selection of modules that I’d like to use: PGA2350 RM2 Wireless & Bluetooth Breakout (SP/CE) Pimoroni RM2 Breakout, CYW43439, WLAN, Bluetooth, SP/CE, RP2040/RP2350, 3-3,3V or somehow Raspberry Pi Radio Module 2 (RM2) Raspberry Pi Radio Module 2, RMC20452T Funkmodul ESP-PROG UART & Flash Adapter Board für ESP8266 Serial and 3V3 source SD Card Reader Adapter Modul für Arduino V2 or Micro SD Card Reader Adapter Modul für Arduino RTC DS3231 Adafruit PCM5102 I2S DAC with Line Level Output - 112dB SNR or PCM5102 DAC Decoder GY-PCM5102 I2S Player Adafruit CH334F Mini 4-Port USB Hub Breakout Doppelseitige Lochrasterplatine 8 x 12 cm 10x 40 Pin 2.54 mm Buchsenleiste einreihig bunt Stiftleisten Sortiment bunt einreihig 40 Pin gerade Molex USB-A-Steckverbinder, USB 2.0 Buchse, THT-Montage, abgeschirmt, rechtwinklig Soldered USB-Typ-A Buchse Breakout Board, THT-Pins Looks fun to me :)) Edited 2026-07-09 05:50 by dddns |

Don't use that scard adapter. You want one with no level conversation |

Thank you! This is better: Micro SD Card Reader Modul mit SPI Schnittstelle, kompakt Edit: Wrong link for DS3231 in first post RTC DS3231 Echtzeituhr-Modul für Arduino (ohne Batterie) Forgot about the HDMI: Adafruit DVI Breakout Board Adafruit DVI Breakout Board - For HDMI Source Devices Edited 2026-07-09 08:04 by dddns |
