[Introduction]：E90-DTU (400SL30L) est une radio de transmission de données sans fil utilisant la technologie de modulation LoRa de qualité militaire. Il dispose d'une variété de méthodes de transmission et fonctionne dans la bande de fréquences (410,125 ~ 493,125 MHz) (par défaut 433,125 MHz). La radio fournit deux types de port de communication série RS485 et TTL, prend en charge l'alimentation cc 8 ~ 28 V ou l'entrée d'alimentation de la batterie au lithium 4,2 V, prend en charge la charge à courant constant inverse.

Item	Tag	Function	Description
1	Battery+	Positive pole of battery	DC 3.0 ~ 5.0V, pay attention to the positive and negative poles of the battery, do not reverse, support the battery charging
2	Battery -	Negative terminal of battery power supply interface
3	DOUT	transistor output	The output wiring mode is NPN, the load voltage is less than 30V, and the maximum allowable current is 100mA
4	GND	Input and output common terminal
5	DIN	DIN dry contact input	Switch input detection
6	TTL-RXD	TTL-3.3V signal input	When using TTL, it is necessary to connect the signal common terminal, and it cannot be used with the RS485 interface at the same time.
