GPIO
Each GPIO can be configured by software as an input or output
Programmable control for GPIO interrupt,
4mA current sink/source capability for 3.3v I/O supply
RTC(Real time clock)
The RTC is an independent 32‐bit hardware timer, providing a continuously running counter
that can be supplied to a customer clock‐calendar and timer interrupt.
GPT(General purpose timer)
A 32‐bit counter with programmable clock divider and pre‐scalar
Input capture for external inputs
Edge‐aligned and Center‐aligned PWM
ADC
The ADC module has a programmable resolution from 10 to 16 bits.
Flexible gain buffer setting of 2x, 1x, 0.5x
Highest throughput rate with 10‐bit resolution is 250ksample/s
UART
UART0 for debug; UART2 used to communicate with other device.
I2C
Three speeds: standard mode(100kb/s), fast mode(400kb/s), high‐speed mode(3.4Mb/s)
Clock synchronization
Master or slave I2C operation, multi‐master, multi‐slave operation, and arbitration support
JTAG
Just for firmware burning
Antenna
When customer selects the on‐board chip antenna, the antenna must away from
metal or high components at least 15mm, and do not put any components or copper under
the antenna, it also can not be shielded by any meal enclosure.
As the simulation result show, the pcb antenna has 1.5dB gain and its S11<‐14dB between
2.4GHz~2.5GHz
The device also supports external antenna. The parameters required are as followed:
Frequency range
2.4G~2.5G
Impedance
50Ohm
VSWR
<2
Return loss
<‐10dB
Connector type
IPEX
Warning
