# Makerdiary nRF52840 Connect Kit
2+
3+
## Introduction
4+
5+
[nRF52840 Connect Kit](https://makerdiary.com/products/nrf52840-connectkit) is an open-source prototyping
6+
kit designed for connected projects. It is built using the nRF52840 SoC, which has protocol support for
7+
Bluetooth LE, Bluetooth mesh, Thread, Zigbee, 802.15.4, ANT and 2.4 GHz proprietary stacks. It provides
8+
Arm TrustZone® CryptoCell cryptographic unit as well as numerous peripherals such as USB 2.0, NFC-A, GPIO,
9+
UART, SPI, TWI, PDM, I2S, QSPI, PWM, ADC, QDEC to support a wide range of applications.
10+
11+
The design is available in an easy-to-use form factor with USB-C and 40 pin DIP/SMT type, including up to
12+
32 multi-function GPIO pins (7 can be used as ADC inputs) and Serial Wire Debug (SWD) port. It features
13+
RGB LED, Buttons, external 64 Mbit QSPI flash and flexible power management with various options for easily
14+
powering the unit from USB-C, external supplies or batteries, and also has Chip antenna and U.FL receptacle
15+
options to support various wireless scenarios.
16+
17+
Refer to [nRF52840 Connect Kit wiki page](https://wiki.makerdiary.com/nrf52840-connectkit) for more details.

## Hardware diagram
22+
23+
The following figure illustrates the nRF52840 Connect Kit hardware diagram. The design is available in
24+
Chip antenna and U.FL receptacle options, both have most of the same components except the antenna
25+
interface.

## Get Involved
30+
31+
We think the best way to learn is by doing. And to help you run CircuitPython on nRF52840 Connect Kit,
32+
we have provided an extensive set of documentation. Find the details [here](https://wiki.makerdiary.com/nrf52840-connectkit/guides/python/).
