# Makerdiary Pitaya Go
2+
3+
>Pitaya Go is a compact and versatile development platform for IoT solutions,
4+
combining the Nordic's high-end multiprotocol SoC nRF52840 and the Microchip's
5+
extreme low power Wi-Fi® network controller ATWINC1500B. It offers a complete
6+
solution for wireless connectivity with IEEE 802.11 b/g/n, Bluetooth 5, Thread
7+
and Zigbee, that is specifically designed for the IoT.
8+
Pitaya Go features a Battery Charger with power path management, 64Mbit ultra
9+
low power QSPI Flash memory, additional NFC-A Tag PCB Antenna, user
10+
programmable RGB LED and Buttons, reversible USB-C Connector and easily
11+
expandable Header Sockets. All these features above make this board an ideal
12+
choice for the next IoT project.

## Installing CircuitPython submodules
18+
19+
Before you can build, you will need to run the following commands once, which
20+
will install the submodules that are part of the CircuitPython ecosystem, and
21+
build the `mpy-cross` tool:
22+
23+
```
24+
$ cd circuitpython
25+
$ git submodule update --init
26+
$ make -C mpy-cross
27+
```
28+
29+
30+
## Building
31+
```sh
32+
$ cd ports/nrf
33+
$ make BOARD=pitaya_go SD=s140 -V=1 -j4
34+
```
35+
36+
# Flashing CircuitPython
37+
38+
The Pitaya Go has a pre-programmed bootloader which can be used to program the
39+
Pitaya Go. Follow [the guide - How to Program Pitaya Go](https://wiki.makerdiary.com/pitaya-go/programming/)
40+
to flash the CircuitPython firmware.
