- LoRa E5benj/ — symbole + footprint pour le socket PLCC-28 du module Seeed LoRa-E5 - Docs/` — notes de conception, brouillons d'empreintes
Le module LoRa est monté sur un socket PLCC-28 plutôt que soudé : remplacement / upgrade sans dessoudage, et fini les ponts entre pins très rapprochées (cf. rapport).
