Finland live train map
Finland live train map is an open source ESP32 PCB design by HekiNav: a 2-layer, 110 × 220 mm board with 326 components (27 distinct parts). It is built around the RT9080, ESP32-C3FH4, SN74LV1T34DBV.
- Made in KiCad with CDFER's JLCPCB KiCad library. - Inspiration for antenna and power system taken from CDFER's live train maps. They are very cool! - Designed to be fabricated and assembled by JLCPCB - PCBA by JLC because tiny components and hundreds of leds are hard to assembl
- Made in KiCad with CDFER's JLCPCB KiCad library. - Inspiration for antenna and power system taken from CDFER's live train maps. They are very cool! - Designed to be fabricated and assembled by JLCPCB - PCBA by JLC because tiny components and hundreds of leds are hard to assemble manually. Also, LCSC components are very cheap with JLC.
- ESP32-C3FH4 (chip) - 4MiB built-in flash - Level Shifter (3V3 data from esp to 5V led data) - TI SN74LV1T34DBVR - Power management - USB VBUS to 5V and 3V3 rails - Mosfet to shut down 5V rail - 239 ARGB LEDs: Xinglight XL-1615RGBC-2812B-S - The -S version…
