Mau cetak sendiri?
Desain ini bisa dicetak dan dirakit lewat Rakitronik dalam jumlah berapa pun, atau dipakai sebagai titik awal papanmu sendiri. Harga di bawah dihitung dari Gerber dan BOM dengan harga part JLC hari ini.
Titik awal sama dengan jawaban awal contoh ini (RS485 1 port, analog 2 kanal, microSD, RTC, surya, 4G).
Harga cetak sedang dihitung dari harga part JLC hari ini dan belum tersedia. Coba lagi sebentar.
