[Introduction]:E104-BT53C3 est un module BLE série vers BLE basé sur la version 5.2 du protocole BLE.Il présente les caractéristiques suivantes: résistance à haute température, petite taille, faible consommation d'énergie, longue distance de transmission et forte capacité anti-interférence.Il fonctionne dans le Bande de fréquence 2,4 GHz. Le module ble est de qualité automobile développé sur la base de la puce EFR32BG22C224F512IM40-C de Silicon Labs. Il peut être utilisé pendant une longue période dans un environnement de -40 ~ + 125 ° C. Le module ble utilise des commandes AT courantes et l'opération est simple et rapide. Les modules ble peuvent être largement utilisés dans les vêtements intelligents, la domotique, la sécurité domestique, les soins de santé personnels, les appareils ménagers intelligents, les accessoires et les télécommandes, les automobiles, l'éclairage, l'Internet industriel, l'acquisition de données intelligentes, le contrôle intelligent et d'autres domaines.
| pin number | Name | Function | Remarks |
| 1 | PB04 | I/0 | GPI0 |
| 2 | PB03 | I/0 | GPI0 |
| 3 | TXD | 0 | Module serial port sender |
| 4 | RXD | I | Module serial port receiver |
| 5 | PB00 | I/0 | GPI0 |
| 6 | PA00 | M0D | Mode configuration: input low level for more than 200ms, the module enters configuration mode: input high level for more than 200ms, the module enters transparent transmission mode. (This pin has an internal pull-up and works in transparent mode by default) |
| 7 | PA01 | SWCLK | users don't need to care |
| 8 | PA02 | SWDI0 | users don't need to care |
| 9 | PA03 | I/0 | GPI0 |
| 10 | PA08 | 0 | Indicates the connection status of the slave (including the role of Beac0n); the pin outputs a low level after the connection is successful; the output is a high level after the connection is disconnected |
| 11 | PA07 | 0 | Indicates the connection status of the host; the pin outputs a low level after the connection is successful; the output is a high level after the connection is disconnected |
| 12 | PA06 | RTS | (Standard hardware flow control Require T0 Send) module output signal, when it is high, it means that the serial port of the module is busy, and the MCU is not allowed to send data to the serial port of the module, and when it is low, it can send data to the module. |
| 13 | PA05 | CTS | Standard hardware flow control (Clear T0 Scnd) module input signal, when it is high, it means that the MCU serial port is busy, the module will not send data to the MCU serial port, and when it is low, it can send data to the MCU. |
| 14 | PA04 | REST0RE | Internal pull-up. Falling edge, and then keep the low level for at least 5 seconds, all parameters will be restored to factory settings and the module will automatically restart |
| 15 | VCC | l | Positive power supply, 1.71~3.8v, 3.3V recommended |
