EKSGCN Series for EYSGCN series Bluetooth Ⓡ low energy Module
TAIYO YUDEN CO., LTD.
Introduction
This evaluation board is applicable for Taiyo Yuden’s Bluetooth ® 4.2 low
energy module, EYSGCN Series.
Serial UART interface and power supply are
possible with one USB cable. And this board has the SWD connector terminal for
software development.
Mounted module

How to use
It is very easy just to tie this board to the PC with a USB cable. It is not
necessary to change the setting of the board. The power supply of the module
supplies by default
3.3V from 3V3OUT of FT232RQ.
For software development
Nordic-DK and Use case
Nordic-DK
http://www.nordicsemi.com/eng/Products/nRF51-DK
**MEMO
- Current measurment**
To measure the current, please cut the shorting 1pin and 2 pin of CN6. And connect an ampere-meter between the pins of connector CN6 to monitor the current directly.
2) About the power supply of the module
When you use external power supply, please supply power from 9pin and 10pin of
CN3.
On this configuration, you cut short circuit 1pin and 2pin of CN5 and should
separate 3V3OUT of FT232RQ.
3) USB to serial UART interface
It needs to install driver of FT232RQ to use USB for UART interface.
The drivers are available on FTDI website.

In addition, by the application development, please assign GPIO as follows.
| GPIO | UART |
|---|---|
| P0.00 | RTS |
| P0.01 | TX |
| P0.02 | CTS |
| P0.03 | RX |
4) Size and Coordinate information
Important notes
The evaluation board included with the Nordic Development Kit uses a 16MHz
clock. Therefore the sample code from Nordic is designed to be used with a
16MHz clock. On the other hand, the EYSGCN series module uses a 32MHz system
clock, making it incompatible with the Nordic sample code (i.e. sample code
does not configure HFCLK: XTALFREQ register for 32MHz). To fix this issue, we
need to write the value 0xFFFFFF00 to the UICR (User Information Configuration
Register) at address 0x10001008. Please note that the UICR is erased whenever
you download a SoftDevice.
The UICR can be written by using the debug tools:
nrfjprog.exe –snr
Or the following code can be added to the SystemInit function in the
system_nRF51.c file, right before launching the TASK_HFCLKSTART task:
if ((uint32_t )0x10001008 == 0xFFFFFFFF) {
NRF_NVMC->CONFIG = NVMC_CONFIG_WEN_Wen << NVMC_CONFIG_WEN_Pos;
while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
(uint32_t )0x10001008 = 0xFFFFFF00;
NRF_NVMC->CONFIG = NVMC_CONFIG_WEN_Ren << NVMC_CONFIG_WEN_Pos;
while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
NVIC_SystemReset();
while (true){}
