Connect VCC, RX, TX and GND to start updating if it’s a TTL downloading cable free of
cold start. Change RX and TX if failed. Usually you need to import the font library and
either one of 1306 and 1106s firmware.
The official website offers 12864 OLED firmware for 1306 and 1106 drivers, with available
languages English, Mandarin and Korean.
ELECFREAKS updates firmware in the official forum and offers third-party firmware to
geeks to test. Please follow ELECFREAKS official forum.

Development announcement
SOI one is a great product, however ELECFREAKS allows geeks to do the secondary
development of SOI one, including its software, hardware and structure. ELECFREAKS highly
supports the secondary development of SOI one, and rewards those who would improve and
upgrade this product.

Electric parameters
The battery requirements are listed below. With a special current-limiting design, SOI one asks
for a minimum current with its voltage in the same category. If the voltage is 12V, the minimum
current should be 1.5A. It shows the same performance if you use 3A battery. The ideal battery is
24V and 3A. To ensure good performance, Voltage below 12V is not advised. Please make sure
there is no short-circuit, otherwise it would damage PCB.

Low voltage protection is suitable for mobile soldering platform powered by a battery. When the
voltage drops to the set buzzer voltage, it’ll continue to function only with a buzz warning. When
it drops to sleep voltage, it’ll be forced to sleep mode with a buzz warning and the soldering iron
