BD3QHR-RDA5087FP Radio

Overview

The RDA5087FP radio's
external antenna doesn't work!!! I haven't tested Type-C, so I don't know if it will work!!! Don't copy my work, just copy the original author's!!! (Copying cost is 130 RMB x 5 (including 30 RMB x 2 for the 3D shell))
I. Declaration:
Based on an open-source project, following the same CERN Open Hardware License as the original project.
Original author's homepage: https://oshwhub.com/und3f1ned/works
Original project link: https://oshwhub.com/und3f1ned/dian-xie-zha

II. Project components
: RDA5087FP chips (50MHz to 115MHz radio) purchased from Taobao, around 1.1 RMB each.
The external antenna, although unusable, was also purchased from Taobao.
The 3D shell was printed by JLCPCB (file below).
Other components came from LCPCB Mall and JLCPCB PCB manufacturing.
III. Project shortcomings:
The external antenna doesn't work... I haven't tested Type-C, so I don't know if it will work... The first version of the button circuit design was wrong, the wires were flying...

I am writing something about interrupts because of DC's invitation. I have only been in contact with 430 for a short time and can only share my own experience with you. Please forgive me if there are
Analog and digital circuits in PCB design
In a circuit, there are both analog circuits and digital circuits. So how do we connect the analog power supply and digital power supply, and the analog ground and digital ground? (In low-frequency ci

Can the STM32F746G-DISCO be connected to a parallel high-speed ADC?
I want to read the data of a 14-bit ADC. The ADC uses parallel communication, with a total of 14 data lines and several control lines. Since I don't have an FPGA and don't know how to use it, I want t
