Hi Lars,

sorry for the delay: can you tell me a little about this boards?

are they a DIY version or a brand board? all of this to know what to change and how to process to add it and test with a github branch before adding it to webflasher?

Hi Ricardo Thank you for reaching out! The Kincony board KC868-A6 is an ESP32 relay board (and I just realized a new revision is out named KC868-A6v3 which is based on the ESP32-S3 chip) that supports Lora on a daughter card. It is available on Aliexpress and https://shop.kincony.com/products/kc868-a6-esp32-6-channel-relay-module A full board description (of the ESP32 based board) is found here : https://www.kincony.com/esp32-6-channel-relay-module-kc868-a6.html The sx1278 daughter card is either sold by Kincony or available through Aliexpress, example https://www.aliexpress.com/item/1005006273594443.html?spm=a2g0o.order_list.order_list_main.40.632b1802BthCWR So why add support for such a board? My intention is to utilize APRS messages to control the output relays of the board through QUERY_Utils. Additional support for inputs may be considered as well. The original idea comes from this project: https://github.com/xssfox/repeaterrescue using the KC868-A4 board (does not support Lora). Combining the iGate software with the ideas from the repeaterrescue project could really expand the uses cases for Lora APRS. Rgds Lars

great Lars,

so lets add it!!!

should we take into account both versions of the boards or just one?

are they the same pinout?

both use the same SX1278 "daughter" board?

[larsgranheim]

I suggest only supporting "KC868-A6-v1.3SP" at this time. The v3 board was released 22 Feb 2025 ( https://www.facebook.com/Kinconykc868/), pinouts look to have changed slightly (from FB picture) and I find no schematics published. It looks like the sx1278 board should be compatible between the versions, but not verified. (Good to note with the sx1278 board is that if bought without pins soldered to the board, the DuPont pin hole pitch is 2.0mm, not the most common 2.54mm pitch) My plan onwards - Add: GPS support over 'serial port' (ttl) -> GPS time allows totp authentication (and/or add ntp time sync if wifi connected) Relay control through pcf8574 library HOTP (and totp?) to secure relay controls over APRS with no encryption and prevent cmd replay Use RTC circuit and battery to retain time when power lost ..other fun stuff like temp support over the digital inputs and more.
